Problems with building libpq for windows

Hi,

I recently downloaded source code for 8.0.0 beta1. When I tried building the libpq for windows, I got some compilation errors. Following the compilation output:
C:\temp\postgresql-8.0.0beta1\src>nmake /f win32.mak

When I looked for the undeclared identifiers, they were not defined anywhere in the source tree. Has anyone faced similar problems? Can someone please tell me how to overcome this issue?

Thank you very much in advance,
Sagar.
