That won't work, for the reasons you describe. How about this idea: modify getgroups.m4 to recognize the Darwin situation and compile a substitute getgroups.c, and modify getgroups.c to work around the Darwin problem by defining a rpl_getgroups that calls the correct Darwin getgroups. It'll take a bit of Darwinish hacking to get this to work, but it should work.
