[plt-scheme] MSVC errors again with MzScheme

As I said I got MzScheme to work... that is until I rebooted. I just
reinstalled MSVS 2003 (to clean up the drive and relocate it) and I'm
still getting the same issues after the bat file is run. I've added the
following to Path:
~\Microsoft Visual Studio .NET 2003\Vc7\bin;

which wasn't added by the bat evidently.
Then it errors out not able to find mspdb71.dll, which I found in
~\Microsoft Visual Studio .NET 2003\Common7\IDE
and moved to my PLT dir.

Now I get the following:

D:\Prog\Scheme\PLT>mzc --cc hello.c
MzScheme compiler (mzc) version 207, Copyright (c) 2004 PLT Scheme, Inc.

d:\Prog\Scheme\PLT\include\scheme.h(109) : fatal error C1083: Cannot open

I'm about ready to start working on getting dev-c++ to work with this...
I'm really not sure why the .bat file isn't working as is indicated by a
quick net search on the problem as well as with Mr. Khorev's input.
Cheers in any event,
