Just FYI, while the above is apparently trivial, the required change isn't.

GCC should be providing information (either via special headers or via 
other debug info or magic sections) that informs GDB of the selected 
size of an int.  GDB can then adjust its configuration accordingly.  See 
other GDB architectures (MIPS, PPC, SH, ...) that do this.
