Apparently it ICEs cc1:

gcc-help:
When building gcc-4.8.1, gcc fails at the 2nd stage libgcc:
configure: error: in
`/cygdrive/i/szsz/tmpp/gcc4/gcc-4.8.1-1/build/i686-pc-cygwin/libgcc':
configure: error: C compiler cannot create executables
See `config.log' for more details.
Makefile:13865: recipe for target `configure-stage2-target-libgcc' failed

Any ideas why xgcc would emit "xgcc: error: unrecognized command line
option ‘-v’"? Also, xgcc seems to be printing execution statistics
instead of creating an output file if I manage to make it work over
stdin "-xc -".
Procmon show it find cc1, after at which it just sits hung.
Anything?
