+/* On OS X 10.6 and later, use the usual getgroups, not the one
+ supplied when _DARWIN_C_SOURCE is defined. _DARWIN_C_SOURCE is
+ normally defined, since it means "conform to POSIX, but add
+ non-POSIX extensions even if that violates the POSIX namespace
+ rules", which is what we normally want. But with getgroups there
+ is an inconsistency, and _DARWIN_C_SOURCE means "change getgroups()
+ so that it no longer works right". The BUGS section of compat(5)
+ says that the behavior is dubious if you compile different sections
+ of a program with different _DARWIN_C_SOURCE settings, so fix only
+ the offending symbol. */

/* On at least Ultrix 4.3 and NextStep 3.2, getgroups (0, NULL) always
fails. On other systems, it returns the number of supplemental
groups for the process. This function handles that special case
