Subject: Detect when the passwd struct is missing pw_gecos
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=110d6985463886ecc53dbafe32e626704ec612cb;p=git.git

Detect when the passwd struct is missing pw_gecos

NO_GECOS_IN_PWENT was documented with other Makefile variables but was only
enforced by manually defining it to the C preprocessor.  This adds support
for detecting the condition with configure and defining the make variable.
