Owen Taylor f832e3484d Switch style of stamp file usage. 
Sat Mar  2 13:26:58 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/Makefile.am: Switch style of stamp file usage.

        * gtk/Makefile.am gtk/typeutils.[ch]: Switch all the exported
        enumeration/fags TYPE variables over to macros for get_type() functions,
        for lazy definition and to get rid of expensive relocations.

        * gtk/gtkiconfactory.[ch] gtk/gtkselection.[ch] gtk/gtkstyle.[ch]
        gtk/gtktextiter.[ch] gtk/gtktexttag.[ch] gtk/gtktreemodel.[ch]
        gtk/gtktypeutils.[ch] gtk/gtkwidget.[ch]: Switch boxed type
        definitions over manually coded get_type() functions.

        * gtk/gtk.def: Updates for above

        * gtk/{genmarshal.pl,makeenums.awk,makeenums.h,maketypes.awk}:
        Remove from CVS, no longer used.

        * configure.in: Remove checks for awk.
