I never got an answer to get past this.
Gaius asked me to:

   find . -name 'M2Reserved.o' -exec nm {} \; -print

and send him the results.

I did and there were two files of this name:
./gcc/gm2/gm2-compiler/M2Reserved.o which did NOT have the symbol 
_M2Reserved_NulName and
./gcc/gm2/gm2-compiler-boot/M2Reserved.o which DID have that symbol.

I'm not sure which part of the build mine got to relative to yours.

P.S.

Also, in order to get as far as I did I had to do a lot of hacking.  Did 
you run into a lot of problems?

I had to:

1) Fuss with an undefined symbol toupper in the files in 
./gcc/gm2/p2c/p2c-src/src: p2c.h and trans.h
I changed an #if 0 to an #if 1 to allow fix for BSD systems.
I also had to edit my_toupper and my_tolower so they actually did stuff 
rather than call _toupper, etc.


2) run ranlib by on a library file:
building gm2/ppg
ld: archive: p2c/p2c-src/src/libp2c.a has no table of contents, add one 
with ranlib(1) (can't load from it)


3) There was a missing directory:

cd gm2 ; \
if echo -DIN_GCC  | grep -e -DCROSS_COMPILE; then \
           AR=`echo ar | sed -e "s/^ //"` ; \
           export AR ; \
           /bin/sh -c 
'../../../gcc-3.3.4+gm2-20041222/gcc/gm2/configure 
--srcdir=../../../gcc-3.3.4+gm2-20041222/gcc/gm2 
--target=powerpc-apple-darwin7.8.0 --program-suffix= 
--includedir=/usr/include' ; \
       else \
           /bin/sh -c 
'../../../gcc-3.3.4+gm2-20041222/gcc/gm2/configure 
--srcdir=../../../gcc-3.3.4+gm2-20041222/gcc/gm2 
--target=powerpc-apple-darwin7.8.0 --program-suffix=' ; \
       fi
/bin/sh: line 1: cd: gm2: No such file or directory
/bin/sh: line 1: ../../../gcc-3.3.4+gm2-20041222/gcc/gm2/configure: No 
such file or directory
make[2]: *** [gm2/gm2config.h] Error 127
make[1]: *** [stage2_build] Error 2
make: *** [bootstrap] Error 2

I went in and created the gm2 directory in gcc in my build directory by 
hand.
Went further.


4) There was a missing executable somewhere
cp: stage2/gm2/cc1gm2: No such file or directory
make[2]: *** [cc1gm2] Error 1
make[1]: *** [stage2_build] Error 2
make: *** [bootstrap] Error 2

Found this in ./gcc/stage1/gm2/p2c/p2c-src/src/p2c.proto
and copied it to gcc/gm2/p2c/p2c-src/src


5) Another need to run ranlib

ld: archive: p2c/p2c-src/src/libp2c.a has no table of contents, add one 
with ranlib(1) (can't load from it)
failed to link gm2/ppg
make[4]: *** [gm2/ppg] Error 1
make[3]: *** 
[/Users/ed/gcc/obj-3.3.4+gm2-20041222/gcc/gm2/gm2-auto/P2Build.mod] Error 2
cp: stage2/gm2/cc1gm2: No such file or directory
make[2]: *** [cc1gm2] Error 1
make[1]: *** [stage2_build] Error 2
make: *** [bootstrap] Error 2

Run ranlib by hand on 
obj-3.3.4+gm2-20041222/gcc/gm2/p2c/p2c-src/src/libp2c.a again.


6) A missing target -liconv which turned out to be a library flag.  I 
finally just made a bogus Makefile target.


I'm sure that there were missed opportunities in the configure stage.  
Unfortunately, I don't know autoconf and automake at all.  If I did that 
would be the most effective way to help.
