At the moment, widl doesn't support generating 64-bit compatible client, 
server and proxy code so doing so would be useless. FWIW, MIDL outputs 
__int64 here instead of long when targeting 64-bit.

Getting support for the Microsoft 64-bit calling convention into 
upstream gcc is the most important requirement for a 64-bit Wine.
