Building libpq on Windows

Hi,

I'm currently trying to do a custom build of Mapserver to get FastCGI
support, and one of our requirements is PostGIS support built into it.
I've been having problems getting it to compile with MS VS 2003 though.
I get the following errors when I type "nmake /f win32.mak":

=================
cd include
if not exist pg_config.h copy pg_config.h.win32 pg_config.h
cd ..
cd interfaces\libpq
nmake /f win32.mak

NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio

Any help would be appreciated.

Thanks,
