* utilunix.c: init_groups(), destroy_groups(), get_user_permissions()
	rewritten to use GTree structure and functions. Add new static helper
	functions mc_gid_compare() and mc_gid_destroy().

	* util.h: Removed deprecated structure user_in_groups.

	* screen.c: Fixed typo in format report error string.

2001-08-31 23:14:21  Timur Bakeyev <mc@bat.ru>

	* utilunix.c: get_user_rights() renamed into get_user_permissions().
	delete_groups() renamed into destroy_groups().
	* util.h: Likewise.
	* screen.c: Likewise.
	* main.c: Likewise.

"... Some ctype macros are valid only for character codes that
isascii says are ASCII (SGI's IRIX-4.0.5 is one such system --when
using /bin/cc or gcc but without giving an ansi option). So, all
ctype uses should be through macros like ISPRINT... If
STDC_HEADERS is defined, then autoconf has verified that the ctype
macros don't need to be guarded with references to isascii. ...
Defining isascii to 1 should let any compiler worth its salt
eliminate the && through constant folding." */
