	getgid32, getgrgid32, getgrnam32, getgroups32, initgroups32, lchown32,
	setgid32, setegid32, getgrent32.
	* grp.cc (grp32togrp16): New static function.
	(getgrgid32): New function.
	(getgrnam32): Ditto.
	(getgrent32): Ditto.
	(getgroups32): Change name of internal function from getgroups.
	(getgroups32): New function.
