Ok, fine, now the linker *again*. I have some lenghty code, if is strip it down I post it here.

Pragmas are included inside the modules (so you dont have to explicitly link against libraries). There is a 1 to 1 mapping with the genuine win32 headers. Example:
winuser.h becomes win32.winuser;
wingdi.h becomes win32.wingdi;
etc...
