Have no idea what this means.  Looking at that line, maybe on i386, or
on linux/cygwin, USE_MAPPED_LOCATION is defined, and we never hit that.

Could you try building a native compiler from our gcc sources?  I don't
know the prerequisites for building gcc on MacOS, but, could you try
building a native gcc from cegcc/src/gcc ?

cd src
mkdir buildirgcc
cd builddirgcc
../gcc/configure
make

If that fails, could you try building a pristine gcc 4.1.0 (the version we
are based on) from gcc.gnu.org, or from apple?  I'm trying to rule out if
it is our local edits, or a general MacOS x gcc 4.1.0 problem.

Did you try a simple hello world app with gcc-3.3?  The error implies that
even that wouldn't work, much less building gcc.  Try looking at the
config.log.  It should give a hint on what is missing.

To my knowledge you would be the first, but most of our components
should work.  binutils, gcc, and gdb should be buildable/usable on MacOS.
What is the arch you are using?
