Hmm, isn't this going to weak havoc for C++?  If I read your diff
correctly, it'll change from

  typedef unsigned long XID;

into what's effectively

  typedef uint32_t XID;

on 32-bit systems.

Now if your system defines uint32_t as:

  typedef unsigned int uint32_t;

this will change how C++ functions that take an XID as one of its
arguments are magled, causing major ABI breakage.
