Certainly on the operating systems that I can recall, your initgroups()
is doing the same thing as the C level initgroups. But if the C level
one is available, it seems more prudent to use it if it's there - gods
only know what some weirdo systems do (shuddering to recall some of 
DEC's "enhanced security" cruft in Ultrix and OSF/1...)
