[Gm2] build fails under cygwin.

[Mark]

Hello,

When I build the latest version (gcc-4.1.2+gm2-20091117.tar.gz) on windows
XP and cygwin the build fails. 

I get the following error for file
gcc-4.1.2+gm2-20091117/gcc/gm2/gm2-libs/RTint.mod:
./xgm2 -fcheck-all -g  -funbounded-by-reference -fpim -fextended-opaque

When I remove the debug information options (-g and -gdwarf-2) the build
is ok.

The following files have similar compilation problems:
gcc-4.1.2+gm2-20091117/gcc/gm2/gm2-libs-iso/RndFile.mod
gcc-4.1.2+gm2-20091117/gcc/gm2/ulm-lib-gm2/std/StdIO.mod

Any idea what the problem is?
