[PATCH 4/6] Fix an "implicit function definition" warning.

Ramsay Jones· Mar 3, 2007, 18:28 UTC · lore

The function at issue being initgroups() from the <grp.h> header file. On Cygwin, setting _XOPEN_SOURCE suppresses the definition of initgroups(), which causes the warning while compiling daemon.c.
