Hi Michael,

ok yesterday I built gm2 on a:

Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; 
root:xnu-1228.9.59~1/RELEASE_I386 i386

and then attempted to build gm2.paranoid (dejagnu wasn't installed -
so I couldn't easily run the regression tests).  I opted for
attempting to 'make gm2.paranoid' and it failed during the link of
stage2/gm2/cc1gm2.

gcc   -g -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes 
-Wmissing-prototypes     -DHAVE_CONFIG_H  -o stage2/gm2/cc1gm2 gm2/gccgm2.o

ld: in gm2/gm2-compiler/gm2.a(M2LexBuf.o), object file contains old DWARF debug 
info - rebuild with newer compiler
collect2: ld returned 1 exit status
make: *** [stage2/gm2/cc1gm2] Error 1

I had to alter:
    ./libstdc++-v3/scripts/make_exports.pl

to use 'c++filt --strip-underscore' rather than 'c++filt
--strip-underscores'.  So I'm now considering rebuilding vanilla
gcc-4.1.2, installing it locally and then building gm2..

Gaius
