Subject: [PATCH] util.h: add missing stdbool header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

C requires the stdbool.h header for the 'bool' type.

Fixes the following build failure under uClibc-ng C library:

.../arm-linux-gcc -DHAVE_CONFIG_H -I. -I..  -I../include -I../include -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os   -c delay.c
In file included from delay.c:55:0:
../include/util.h:73:1: error: unknown type name ‘bool’
 bool setsock_blocking(int fd, bool blocking);
 ^

[Thomas: add AC_PROG_CC_C99, since C99 is needed for the bool type.]
