compile PGSQL in WinXP SP1

Hello,

I am begginer in PostgreSQL, but I need to develop in Win32.

1. I download file postgresql-snapshot.tar.gz
2. I follow instructions on PostgreSQL documentation
3. cd /src
4. nmake /f win32.mak

but error occured...

tab-complete.c
mbprint.c
        link.exe @C:\DOCUME~1\header\LOCALS~1\Temp\nme02748.
