I've built the 'lib64'  it's ok,
make -fwin64.mak  for 'druntime and phobos'
but I've built the 
'lib32mscoff'(druntime32mscoff.lib,gcstub32mscoff.obj,phobos32mscoff.lib)

  use 'make -fwin64.mak MODEL=32mscoff'

but get some errors:
this is my bat file info:

set lib=C:\Program Files (x86)\Microsoft Visual Studio 
10.0\VC\lib;C:\Program Files (x86)\Microsoft Visual Studio 
10.0\VC\atlmfc

\lib;C:\Program Files (x86)\Microsoft 
SDKs\Windows\v7.0A\Lib;H:\D\dmd2\windows\libms32coff

dmd -c -release -m32mscoff a.d
link   a.obj  /machine:x86 /OUT:a.exe   druntime32mscoff.lib 
gcstub32mscoff.obj phobos32mscoff.lib

It works on vs2010:   %comspec% /k ""C:\Program Files 
(x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"" x86

It can get the a.obj

dumpbin a.obj ,it's COFF type.
