reverted raja's changes, since they leaked a struct passwd contents buffer

Browse Source 
Sun Jan 24 10:33:30 1999  Tim Janik  <timj@gtk.org>

        * gutils.c (g_get_any_init): reverted raja's changes, since they leaked
        a struct passwd contents buffer and for the rest mostly substituted a
        while loop with a bunch of gotos.
        restored the getpwuid() code to what we had after my recent clean ups
        ("Sat Jan 23 02:14:28 1999 Tim Janik"), module yosh's recent changes.
        to feature solaris behaviour of directly returning errno, we don't
        modify error anymore if it's > 0 and simply reset errno.
        don't reset g_home_dir for !NATIVE_WIN32 && !NATIVE_WIN32.
