+
+This patch from Fred Fish to GNAT may make building simpler.  We haven't
+tested it.
+
+> I put a very short blurb in the faq.  GNAT is complicated enough that
+> we should probably write a whole page on how to build/install it.
+
+You may want to use some or all of these patches:
+
+       * Make-lang.in (gnattools): Depends upon GCC_PARTS.
+       (ada.start.encap): Depends upon gnattools.
+       (ada.rest.encap): Depends upon gnatlib.
+       * Makefile.in (../stamp-gnatlib1): Since we are still in the rts
+       subdir when the rule runs, we need to touch ../../stamp-gnatlib1.
+       (../stamp-gnatlib1): Don't unconditionally remove the rts directory,
+       create it if one does not exist.
+       (gnatlib): Remove superflous leading blank char at *-*-pe line.
+       * a-init.c: Define NULL if not yet defined.
