The prototype I gave for initgroups() which was documented in the AIX 4.1 info

page conflicted with the real one that comes from grp.h on Solaris 2.6.
Adjusted it so the local prototype is correct on both (hopefully all)
platforms.  Also added an include of <unistd.h>, which is where initgroups()
lives on HP-UX 10.20.
