Building extensions on Windows using VS2008

Hi!

I was trying to build PostgreSQL 9.0.1 using VS2008. I am having problems
building the C extensions. I could build the main package, though.

Although, I can get a DLL by including the header files from postgres, that
DLL is quite not usable. When I try to create a function inside
psql, I get an error such as:
ERROR: could not find function "<function-name>" in file <dll-name>

Although the same C source file can be built using MinGW and is usable that
way. I don't want to use MinGW as I learn that it supports
only 32-bit binaries (which has performance implications).

Here is the CL command line I'm using to compile:
cl /I \pgsql\include\server /I \pgsql\include\server\port\win32 /LD
\pgsql\lib\postgres.lib <c-filename>
