-The following patches are needed in order to build GNAT with EGCS.
-
-These patches were tested with egcs-980308 and gnat-3.10p on a mips-sgi-irix6.3
-system.  The gnat build succeeded as per the instructions in the gnat
-README.BUILD file for building one library, except that CFLAGS="-O -g" and
-GNATLIBCFLAGS="-O -g" were substituted for the recommended "-O2" so that the
-build could be debugged.  There was no attempt to run the resulting build
-against any testsuite or validation suite.

-Developers Notes:
-
-Every use of sizetype in the Ada front end should be checked to see if perhaps
-it should be using bitsizetype instead.  The change to maybe_pad_type is just
-a hack to work around this problem, and may not be desirable in the long term.
-
-There are many places in the Ada front end where it calls operand_equal_p to
-see if two type sizes are the same.  operand_equal_p fails if the two
-arguments have different TYPE_MODEs.  sizetype and bitsizetype can have
-different TYPE_MODEs.  Thus this code can fail if one type size is based
-on sizetype, and the other is based on bitsizetype.  The change to
-maybe_pad_type fixes one very critical place where this happens.  There may
-be others.

-
-	* a-gtran3.c (maybe_pad_type): Convert both size and orig_size to
-	sizetype if they have differing modes.
-	* a-misc.c (gnat_tree_code_type): Change from string to char array.
-	(init_lex): Delete realloc calls for tree_code_* globals.  Adjust
-	bcopy call for gnat_tree_code_type change.
-	* a-tree.def: Adjust for tree_code_* type changes.
-
-	* a-misc.c (init_lex): Rename to init_parse.

-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.
