Compiling libpgtcl.dll

Hello:
Is there some document describing how to compile
libpgtcl.dll? I've tried nmake /f win32.mak (w2k, MSVC++ 6.0) and
fails misserably:

No configuration specified. Defaulting to libpgtcl - Win32 Release.
link.exe @C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\nma01160.

Any ideas?
