*****WARNING**********
	starting at gcc V1.37 gcc-cc1.ttp and gcc-cpp.ttp use a _stksize = -1L
do not try to adjust these. it will adjust to the amount of memory available
in your machine
(see Changelog, crt0.c and malloc.c in the library sources for details)

***WARNING**
	if you got gcc-1.37 source from prep.ai.mit.edu or ohio-state,
then you must first apply two patches in patch1.137 and patch2.137: this
patch is relevant to both atari and non-atari versions of the compiler.
if you grabbed the gcc-1.37 source from dsrgsun, then these patches are already
applied.
	if you got gcc-1.37.1 from prep or ohio-state, or you have already
applied the gcc.diff-1.37-1.37.1 patch on prep,  then you only need
to apply patch2.137.

----------------------------------------------------------------------------

This is the README file for the GNU native/cross compiler. Diffs are 
with respect to GCC V1.37.1

	-configuration:
		copy all the files from the gcc v1.37 distribution
		into a directory called SRC (i created symbolic links between
		the files).
		copy all the files from the gcc v1.37 distribution
		     sub-directory config into SRC/config		
		copy all the files in this directory into SRC.
		copy xm-atari.h and tm-atari.h into SRC/config/
		cd to SRC
		Apply the diffs using larry walls patch program
			patch < gcc-137.diff
		make the following links in SRC
			config.h to config/xm-atari.h
			tm.h to config/tm-atari.h
			aux-output.c to config/out-m68k.c
			md to config/m68k.md

		edit Makefile.* to make sure the following
		are defined appro.:
		CROSSDIR -- the home directory of the cross dev. system

		edit gcc.c xm-atari.h & tm-atari.h and replace all
		instances of the string "/dsrg/bammi/cross-../..."
		with CROSSDIR/... (ie. the same string as CROSSDIR above
		plus whatever was there after /dsrg/bammi/cross-.../ ).

	-if you already have a native tos-gcc and want to use
	 that to make new tos executables, skip the next few
	 steps that make the cross-compiler system.
	 Please note that you will not be able to compile the
	 compiler itself on a St with less that 2.5 M of memory.

	-make cross compiler by
		make -f Makefile
	will make and install cpp, cc1  and gcc

	-clean out the directory by
		make -f Makefile clean
	- go and make a cross-gas cross-ld and cross-as
	- make the tos gcc libraries using the cross-compiler
	  system you made above.

	- to make tos atari st executables
	   - make and install cross compiler as above (or use your native
		tos-gcc compiler)
	   - make by
		make -f Makefile.st

Please note: *.c files in this directory are the already patched files
for the gcc-src directory.
