I just realized that the patch I have tried to post, twice, for g++ did not
arrive with my message.  This is another attempt send the same patch.

This patches g++ to prevent it from linking against libm.a, more information
is available in the "Major bug -- Exception handling broken" thread of the
cygwin mailing list.
