When compiling a testdir with argp and strerror_r-posix on a glibc system, I
get this warning:
argp-help.c:1921: warning: assignment makes pointer from integer without a cast
This patch fixes it.
2011-05-29 Bruno Haible <address@hidden>
argp: Allow coexistence with strerror_r-posix module.
* lib/argp-help.c (__argp_failure): If strerror_r is defined as a macro
(either to __xpg_strerror_r by glibc's <string.h> or to rpl_strerror_r
by gnulib's <string.h> replacement), assume it has the POSIX signature,
not the glibc signature.
