OK.  Thanks.

If it's part of something crosstool already built, I don't know.  I was
building with demo-ppc750.sh.  If it's the gcc on my path, that's:

  # gcc -v
  Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
  gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)

Yes.

I'm not sure I've got Cygwin, I don't play with imitation UNIX much. 
I'm building tools for someone else.
