Re: [Gm2] gm2 on gcc-4.7.3 status

[Christoph Schlegel]

Hello Gaius,

using the tarball (gcc-4.7.3+gm2-20140723.tar.gz) I get

                === gm2 Summary ===

# of expected passes            8058
# of unexpected failures        1381
# of unresolved testcases       61

for the Cygwin32 platform.

Regards,
Christoph
