Under cygwin, configure doesn't do a good job of guessing the --host and
--target designations. Supposing that you know it's going to default those
to i586-pc-cygwin32, it would be a good idea to make sure that the implied
include directories are populated prior to building. I suppose these would
be /usr/local/i586-pc-cygwin32/include and
/usr/local/lib/gcc-lib/i586-pc-cygwin32/2.95.2/include. Actually, if you are
using a i586-cygwin32 compiler to build a i586-pc-cygwin32 compiler, it may
work best to install a cygwin snapshot of the i586-pc-cygwin32 variety,
'configure --host=i586-cygwin32 --target=i586-pc-cygwin32','make
LANGUAGES=c','make LANGUAGES=c' install, thus accomplishing the creation of
the necessary directories, then reconfigure with --host=i586-pc-cygwin32,
'make LANGUAGES=c bootstrap-lean', following up by 'make LANGUAGES='c++ f77'
if those are the ones you want. I would expect trouble later on if you build
a i586-pc-cygwin32 clone of the i586-cygwin32 setup, without the snapshot
changes. When you say the configure works fine, did you check to make sure
that /usr/local/build/gcc-2.95.2/gcc/Makefile etc were done? I'm sure this
will create disagreements, but I'm not certain exactly what you are trying to
do. If you are trying to rebuild Mumit Khan's version of the compilers, you
will need his source patches. It's been quite a while since I ran configure
under bash and make-3.75, so I'm not sure what's going to happen.
