Subject: [PATCH] Create autotools plumbing for SoftEther.

Add autoconf and automake capabilities to SoftEther so that it can be built
like this:

	# autoreconf --force --install
	# ./configure
	# make install DESTDIR=/tmp/softether

All standard configure parameters are supported, plus:

	# ./configure --enable-debug

Autotools support makes porting, cross compiling, and optimization much easier.

These GNU autoconf-archive components are used for dependency checking:

  * ax_check_openssl.m4
  * ax_check_zlib.m4
  * ax_lib_readline.m4
  * ax_pthread.m4
  * ax_with_curses.m4

+#   AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
+#
+# DESCRIPTION
+#
+#   Look for OpenSSL in a number of default spots, or in a user-selected
+#   spot (via --with-openssl).  Sets
+#
+#     OPENSSL_INCLUDES to the include directives required
+#     OPENSSL_LIBS to the -l directives required
+#     OPENSSL_LDFLAGS to the -L or -R flags required
+#
+#   and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
+#
+#   This macro sets OPENSSL_INCLUDES such that source files should use the
+#   openssl/ directory in include directives:
+#
+#     #include <openssl/hmac.h>

+# SYNOPSIS
+#
+#   AX_CHECK_ZLIB([action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+#   This macro searches for an installed zlib library. If nothing was
+#   specified when calling configure, it searches first in /usr/local and
+#   then in /usr, /opt/local and /sw. If the --with-zlib=DIR is specified,
+#   it will try to find it in DIR/include/zlib.h and DIR/lib/libz.a. If
+#   --without-zlib is specified, the library is not searched at all.
+#
+#   If either the header file (zlib.h) or the library (libz) is not found,
+#   shell commands 'action-if-not-found' is run. If 'action-if-not-found' is
+#   not specified, the configuration exits on error, asking for a valid zlib
+#   installation directory or --without-zlib.
+#
+#   If both header file and library are found, shell commands
+#   'action-if-found' is run. If 'action-if-found' is not specified, the
+#   default action appends '-I${ZLIB_HOME}/include' to CPFLAGS, appends
+#   '-L$ZLIB_HOME}/lib' to LDFLAGS, prepends '-lz' to LIBS, and calls
+#   AC_DEFINE(HAVE_LIBZ). You should use autoheader to include a definition
+#   for this symbol in a config.h file. Sample usage in a C/C++ source is as
+#   follows:
+#
+#     #ifdef HAVE_LIBZ
+#     #include <zlib.h>
+#     #endif /* HAVE_LIBZ */

+# SYNOPSIS
+#
+#   AX_LIB_READLINE
+#
+# DESCRIPTION
+#
+#   Searches for a readline compatible library. If found, defines
+#   `HAVE_LIBREADLINE'. If the found library has the `add_history' function,
+#   sets also `HAVE_READLINE_HISTORY'. Also checks for the locations of the
+#   necessary include files and sets `HAVE_READLINE_H' or
+#   `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or
+#   'HAVE_HISTORY_H' if the corresponding include files exists.
+#
+#   The libraries that may be readline compatible are `libedit',
+#   `libeditline' and `libreadline'. Sometimes we need to link a termcap
+#   library for readline to work, this macro tests these cases too by trying
+#   to link with `libtermcap', `libcurses' or `libncurses' before giving up.
+#
+#   Here is an example of how to use the information provided by this macro
+#   to perform the necessary includes or declarations in a C file:
+#
+#     #ifdef HAVE_LIBREADLINE
+#     #  if defined(HAVE_READLINE_READLINE_H)
+#     #    include <readline/readline.h>
+#     #  elif defined(HAVE_READLINE_H)
+#     #    include <readline.h>
+#     #  else /* !defined(HAVE_READLINE_H) */
+#     extern char *readline ();
+#     #  endif /* !defined(HAVE_READLINE_H) */
+#     char *cmdline = NULL;
+#     #else /* !defined(HAVE_READLINE_READLINE_H) */
+#       /* no readline */
+#     #endif /* HAVE_LIBREADLINE */
+#
+#     #ifdef HAVE_READLINE_HISTORY
+#     #  if defined(HAVE_READLINE_HISTORY_H)
+#     #    include <readline/history.h>
+#     #  elif defined(HAVE_HISTORY_H)
+#     #    include <history.h>
+#     #  else /* !defined(HAVE_HISTORY_H) */
+#     extern void add_history ();
+#     extern int write_history ();
+#     extern int read_history ();
+#     #  endif /* defined(HAVE_READLINE_HISTORY_H) */
+#       /* no history */

+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+# SYNOPSIS
+#
+#   AX_WITH_CURSES
+#
+# DESCRIPTION
+#
+#   This macro checks whether a SysV or X/Open-compatible Curses library is
+#   present, along with the associated header file.  The NcursesW
+#   (wide-character) library is searched for first, followed by Ncurses,
+#   then the system-default plain Curses.  The first library found is the
+#   one returned.
+#
+#   The following options are understood: --with-ncursesw, --with-ncurses,
+#   --without-ncursesw, --without-ncurses.  The "--with" options force the
+#   macro to use that particular library, terminating with an error if not
+#   found.  The "--without" options simply skip the check for that library.
+#   The effect on the search pattern is:
+#
+#     (no options)                           - NcursesW, Ncurses, Curses
+#     --with-ncurses     --with-ncursesw     - NcursesW only [*]
+#     --without-ncurses  --with-ncursesw     - NcursesW only [*]
+#                        --with-ncursesw     - NcursesW only [*]
+#     --with-ncurses     --without-ncursesw  - Ncurses only [*]
+#     --with-ncurses                         - NcursesW, Ncurses [**]
+#     --without-ncurses  --without-ncursesw  - Curses only
+#                        --without-ncursesw  - Ncurses, Curses
+#     --without-ncurses                      - NcursesW, Curses
+#
+#   [*]  If the library is not found, abort the configure script.
+#
+#   [**] If the second library (Ncurses) is not found, abort configure.
+#
+#   The following preprocessor symbols may be defined by this macro if the
+#   appropriate conditions are met:
+#
+#     HAVE_CURSES             - if any SysV or X/Open Curses library found
+#     HAVE_CURSES_ENHANCED    - if library supports X/Open Enhanced functions
+#     HAVE_CURSES_COLOR       - if library supports color (enhanced functions)
+#     HAVE_CURSES_OBSOLETE    - if library supports certain obsolete features
+#     HAVE_NCURSESW           - if NcursesW (wide char) library is to be used
+#     HAVE_NCURSES            - if the Ncurses library is to be used
+#
+#     HAVE_CURSES_H           - if <curses.h> is present and should be used
+#     HAVE_NCURSESW_H         - if <ncursesw.h> should be used
+#     HAVE_NCURSES_H          - if <ncurses.h> should be used
+#     HAVE_NCURSESW_CURSES_H  - if <ncursesw/curses.h> should be used
+#     HAVE_NCURSES_CURSES_H   - if <ncurses/curses.h> should be used
+#
+#   (These preprocessor symbols are discussed later in this document.)
+#
+#   The following output variable is defined by this macro; it is precious
+#   and may be overridden on the ./configure command line:
+#
+#     CURSES_LIB  - library to add to xxx_LDADD
+#
+#   The library listed in CURSES_LIB is NOT added to LIBS by default. You
+#   need to add CURSES_LIB to the appropriate xxx_LDADD line in your
+#   Makefile.am.  For example:
+#
+#     prog_LDADD = @CURSES_LIB@
+#
+#   If CURSES_LIB is set on the configure command line (such as by running
+#   "./configure CURSES_LIB=-lmycurses"), then the only header searched for
+#   is <curses.h>.  The user may use the CPPFLAGS precious variable to
+#   override the standard #include search path.  If the user needs to
+#   specify an alternative path for a library (such as for a non-standard
+#   NcurseW), the user should use the LDFLAGS variable.
+#
+#   The following shell variables may be defined by this macro:
+#
+#     ax_cv_curses           - set to "yes" if any Curses library found
+#     ax_cv_curses_enhanced  - set to "yes" if Enhanced functions present
+#     ax_cv_curses_color     - set to "yes" if color functions present
+#     ax_cv_curses_obsolete  - set to "yes" if obsolete features present
+#
+#     ax_cv_ncursesw      - set to "yes" if NcursesW library found
+#     ax_cv_ncurses       - set to "yes" if Ncurses library found
+#     ax_cv_plaincurses   - set to "yes" if plain Curses library found
+#     ax_cv_curses_which  - set to "ncursesw", "ncurses", "plaincurses" or "no"
+#
+#   These variables can be used in your configure.ac to determine the level
+#   of support you need from the Curses library.  For example, if you must
+#   have either Ncurses or NcursesW, you could include:
+#
+#     AX_WITH_CURSES
+#     if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
+#         AC_MSG_ERROR([requires either NcursesW or Ncurses library])
+#     fi
+#
+#   If any Curses library will do (but one must be present and must support
+#   color), you could use:
+#
+#     AX_WITH_CURSES
+#     if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then
+#         AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])

+#
+#   Certain preprocessor symbols and shell variables defined by this macro
+#   can be used to determine various features of the Curses library.  In
+#   particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
+#   library found conforms to the traditional SysV and/or X/Open Base Curses
+#   definition.  Any working Curses library conforms to this level.
+#
+#   HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
+#   library supports the X/Open Enhanced Curses definition.  In particular,
+#   the wide-character types attr_t, cchar_t and wint_t, the functions
+#   wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
+#   are checked.  The Ncurses library does NOT conform to this definition,
+#   although NcursesW does.
+#
+#   HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
+#   supports color functions and macros such as COLOR_PAIR, A_COLOR,
+#   COLOR_WHITE, COLOR_RED and init_pair().  These are NOT part of the
+#   X/Open Base Curses definition, but are part of the Enhanced set of
+#   functions.  The Ncurses library DOES support these functions, as does
+#   NcursesW.
+#
+#   HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
+#   library supports certain features present in SysV and BSD Curses but not
+#   defined in the X/Open definition.  In particular, the functions
+#   getattrs(), getcurx() and getmaxx() are checked.
+#
+#   To use the HAVE_xxx_H preprocessor symbols, insert the following into
+#   your system.h (or equivalent) header file:
+#
+#     #if defined HAVE_NCURSESW_CURSES_H
+#     #  include <ncursesw/curses.h>
+#     #elif defined HAVE_NCURSESW_H
+#     #  include <ncursesw.h>
+#     #elif defined HAVE_NCURSES_CURSES_H
+#     #  include <ncurses/curses.h>
+#     #elif defined HAVE_NCURSES_H
+#     #  include <ncurses.h>
+#     #elif defined HAVE_CURSES_H
+#     #  include <curses.h>
+#     #else
+#     #  error "SysV or X/Open-compatible Curses header file required"
+#     #endif
+#
+#   For previous users of this macro: you should not need to change anything
+#   in your configure.ac or Makefile.am, as the previous (serial 10)
+#   semantics are still valid.  However, you should update your system.h (or
+#   equivalent) header file to the fragment shown above. You are encouraged
+#   also to make use of the extended functionality provided by this version
+#   of AX_WITH_CURSES, as well as in the additional macros
+#   AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM.
