I do not believe this can be solved with Microsoft's compilers because
they do not understand the inline assembly syntax used by GMP. The Intel
C++ compiler release 10 is supposed to handle it, search the list for some
info Brian Gladman did provide on that about 6 weeks ago. Visual Studio
2005's C/C++ compiler also allegedly removed inline assembly support in
general, but I am not 100% on that.

There is experimental 64 bit support via MinGW, but I haven't tried it out
due to lack of time. I doubt the 64 bit masm will understand the assembly
syntax used, but I am willing to be proven wrong on that one.

Yep, as far as I know that is the only way to get a 64 bit GMP on Windows
working at the moment. Since you are using the Microsoft compilers anyway
I would suggest using Brian's project files. If you get it to work via
Interix please let us know.
