I don't know about building gcc as native windoze application,
but I can give some tips for building gcc for dos (on dos or 
windoze dos-box).

First, you will need some djgpp packages:
djdev, sed, gnu-make, maybe bash (I have it all, so
I can not say what is the minimum). _Install and configure properly_
(read readme.1st and faq it is all there).

Then, unpack gcc2721s.zip (preserve directories structure).

Now, some dos commands:
cd gnu\gcc-2721\config\msdos
configur.bat go32

To run configur.bat from gnu\gcc-2721 you will need to edit
both configur.bat. Changes are:
call config\msdos\configure <- call config\msdos\configur.bat
and
if not exist config\msdos\configure.bat <- if not exist config\msdos\configur.bat

Now, you should be in gnu\gcc-2721 directory.
Edit makefile (there are 3 places where backslash is used instead of slash)
$(srcdir)\bytecode.def  should be replaced with  $(srcdir)/bytecode.def

Run  make CFLAGS=-O2   and have a rest (be sure you run gnu-make).
Without -O2 or with -g it won't work (but maybe it will work with -O,
I didn't try).  Now, you have a chance that everything
(xgcc, cc1, cc1obj, libgcc.a) will be built successfully.
With Windoze 95 make sure you don't run another dos-box
(I did and then have to reboot). And sometimes 'make' may
complain about dpmi handlers (bug in Windoze dpmi server!?).
Then you may reboot ;) and start make again (don't forget -O2).
I think there is no need in building other stages, but
if you want to, then copy [gcc] section to [xgcc]
in djgpp.env and edit COMPILER_PATH, e.g. if you build
in c:\gnu\gcc-2721, then compiler path for building stage2
would be c:\gnu\gcc-2721\stage1

I'm sure that original distribution was built with cross-compiler
on Unix.

Now, you have a lot of info :)
Hope, it will help,
                   Mike.
