I'm not sure if the "LANGUAGES=" expression still works.  I have a feeling that
gcc2.95 uses the "--enable-languages=" expression as a configure argument.  Try
it if the LANGUAGES expression doesn't work.

To answer Greg's original question:
You must have the i386-coff headers and runtime libraries preinstalled in
$prefix/$target/include and $prefix/$target/lib.  An alternative is to use the
--with-headers option to point to the target headers.  It will then copy them to
the installation directory during the "make install" phase.
