I don't think there's any official documentation, however, here are the
steps I followed to get gcc to build successfully. It was rather confusing.
You need to have bash; I don't think you can build without it.
Note that gcc won't build on an LFN system, currently. I presume this will
change when the zip file is made to include the long versions.
Also, gxx is not part of gcc per se, but one of the utils. All it does is
something like:
gcc $@ -lgpp -lstdcx -lm
in shell script format. You don't need to rebuild gxx.

1. Unpack gcc2721s.zip
2. Apply any patches you want, for instance stabs.
3. In the gnu/gcc-2721 directory, run
    configur go32
4. There are a few problems with the makefiles. Apply the patches I've
included below.
5. In the base gcc directory, run
    make "CFLAGS=[whatever]"
6. Change to the cp subdirectory
7. Run:
    make "CFLAGS=[whatever]"
8. Back in the base gcc directory (cd ..), copy the binaries
    cp cc1.exe ../../bin
    cp cc1plus.exe ../../bin (optional, only if you want C++)
    cp cc1obj ../../bin (optional, only if you want Objective-C)
    cp cccp.exe ../../bin/cpp.exe
    ln -s ../../bin/cpp.exe ../../bin/cccp.exe (optional)
    cp xgcc.exe ../../bin/gcc.exe
    cp libgcc.a ../../lib (is this really necessary?)

Patches:
  a. This patch should be applied to gnu/gcc-2721/makefile

Hope this helps; hope you get GCC working soon.
