Hi John,

thanks for reporting this.  I've rebuilt the gm2/gm2-libs/configure
which seems to have generated a more bourne shell compatible script and
have just checked this into cvs.

ok, probably better to omit the -O2 option at present.

gm2 creates a temporary C program which contains main() and makes
calls to all the imported modules - with the final call to the top
level modula-2 program module.

For example on my GNU/Linux Debian box it looks like this:

I think I'd capture your equivalent commands issued by gm2, copy them
to a shell script and change the temporary files to easier to read
names.  Then I'd check in turn to see these intermediate files
contain sensible info

hope this helps,

:-) sounds satisfying!
