Subject: Don't check for posix_spawn() or posix_spawnp() if we were unable
X-Git-Tag: SUDO_1_8_16^2~12
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4b079ee7e6171e26b2fc11a7863708fde0a6bef5;p=sudo

Don't check for posix_spawn() or posix_spawnp() if we were unable
to find spawn.h.  This should only be a problem on systems with
broken headers.  Bug #730
