| Subject: [PATCH] spawn: fix link error on uclibc |
| |
| * m4/spawn_h.m4 (gl_HAVE_POSIX_SPAWN): use AC_SEARCH_LIBS, |
| to incorporate -lrt if needed (on uclibc for example). |
| * modules/posix_spawn: Reference the substituted LIB. |
| |
| Patch status: suggested by gnulib maintainer |
| (http://article.gmane.org/gmane.comp.lib.gnulib.bugs/33610), not in upstream |
| gnulib yet |
| |
| This issue should be fixed in coreutils version 8.23. |
