OK, I figured this out. When I saw your mount table I copied the 
  mount C:/mingw /mingw
This got me past that error when I do a make bootstrap. Now I have,
  ORIGINAL_AS_FOR_TARGET = /mingw/mingw32/bin/as
  ORIGINAL_LD_FOR_TARGET = /mingw/mingw32/bin/ld
  ORIGINAL_NM_FOR_TARGET = /mingw/mingw32/bin/nm
similar to yours.

Unfortunatly it's not. Although I must be getting closer.

$ PATH=/mingw/bin:$PATH which sh
/usr/bin/sh

$ PATH=/mingw/bin:$PATH df /usr/bin
Filesystem           1K-blocks      Used Available Use% Mounted on
C:\cygwin\bin         40957684  38423000   2534684  94% /usr/bin

So, I'm using cygwin's sh, I'm pretty sure that's what you wanted.

How is your build dir rooted (is it binmode)? 

That's a good question. I hadn't thought of that.

$ df $PWD
Filesystem           1K-blocks      Used Available Use% Mounted on
C:\cygwin             40957684  38423000   2534684  94% /

$ mount  
C:\cygwin on / type system (binmode)

If I do 
export PATH=/mingw/bin:$PATH

../gcc/configure \
--with-gmp=c:/msys/1.0/home/bobbybrasko/gcc/gmp/gmp \
--with-mpfr=c:/msys/1.0/home/bobbybrasko/gcc/mpfr/prefixdir \
--with-gcc  --enable-libgomp --host=mingw32 \
--build=mingw32 --target=mingw32 --with-arch=i486 \
--with-tune=i686 --disable-werror --prefix=/mingw \
--with-local-prefix=/mingw --enable-threads --disable-nls \

-enable-shared --enable-version-specific-runtime-libs 2>&1 | tee
configure-out.txt

make  CXXFLAGS="-mthreads -O2" bootstrap  2>&1 | tee make-out.txt

I now get to the same error message without the Makefile problem.

if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

Are you doing anything with a sysroot? or did you setup the i686
directory special somehow? What about the --enable-shared? I was under
the impression that didn't work with mingw.
