Was |int| always thought to be 32bit ?

Appearantly at one time there used to be X implementations for DOS
where int was 16bit unless you used a DOS extender and ran in protected
mode. I'm not sure if any Xserver implementation was real mode, though.
The use of short as 'it's 16bit' is rather poor. Fixed sizes should
be taken form system headers where avaialble or defined in an X header.

A bigger problem however arises from the careless interchange of int 
and long in some parts of the code. 
It makes the VSW4 test suite fail in some tests (one even ends up in
an endless loop) on 64bit BE platforms.
Since the problem exists in the server drawable structure a fix would
either break the internal server ABI or would require to hand cast
assignments all over the code :-(
