I am writing a software for Linux/Unix which could benefit from execvpe() C function. But this function is defined only when -D_GNU_SOURCE. Question 1: Should I ALWAYS use -D_GNU_SOURCE for compiler options no matter what are user options? Question 2: Should I check existence of execvpe() by checking #if _GNU_SOURCE or with AC_CHECK_FUNC(execvpe)? Question 3: Other advice? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
