Suhaib Siddiqui had sent me the CD layout, but I just haven't had time 
to look at it yet.

Few things I had forgotten to ask him, so I'll ask now:

1. What are the mount points guaranteed to be at installation time?
   (ie., is there a / that points to anything useful? Is there a
   /usr/include, /usr/bin? Or is everything in /bin).

2. Output of CD gcc:
   
   $ gcc -v
   $ gcc -print-search-dirs
   $ gcc -v -o hello.exe hello.c
   
   [ hello.c can be any old hello world program ]

Given this, I can build a distribution -- if there's interest of course.
So far, there hasn't been. 

My recommendation:
 
- get the gcc-2.95.2 source distro
- get x86-win32 patches from my site:
  ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/gcc-2.95.2/patches/
- build it:
    
    $ cd ~/src
    $ tar zxf /tmp/gcc-2.95.2.tar.gz
    $ cd gcc-2.95.2
    $ patch -p1 -s < /tmp/gcc-2.95.2-x86-win32.diff
  
  The file gcc-2.95.2-x86-win32.diff is included in my patchset. 
    
    $ mkdir /tmp/gcc-2.95.2-build
    $ cd /tmp/gcc-2.95.2-build
    $ ~/src/gcc-2.95.2/configure --prefix=/usr/local/gcc-2.95.2 \
      --enable-languages=c,c++,f77,objc,java \
      i686-cygwin
  
  Of course, you may want a different prefix, or the default (/usr/local).

    $ make 
    $ make install

This should work in theory, but I have no way to tell.

Regards,
Mumit
