Hi PostgreSQL hackers,

support for Mingw-w64 compiler was added to postgres with commit 91812df. 
Unfortunately only the 64 bit output is working right now. This issue was 
already highlighted with initial patch in

Mingw-w64 uses the same header files for 32 and 64 bit compiles. So the same 
conditions apply to mingw-w32 bit as for the WIN64 case. In WIN64 "WSAAPI" is 
defined to nothing, but in 32 bit to stdcall, so it needs to be used in the 
accept-parameter check, too. Maybe you prefer PASCAL instead of WSAAPI in 

I tested successful compilation for the following platforms:
- i686-w64-mingw32 - gcc v4.6.1
- x86_64-w64-mingw32 - gcc v4.6.1
- i586-mingw32msvc - gcc v4.4.4
- x86_64-linux-gnu - gcc v4.6.1

Kind regards,
Lars Kanis
