Actually, if you want to guarantee the size of an integer variable with gcc,
you can do, for example, this:
typedef int __attribute__((mode(SI))) siint;
which creates a 32-bit signed integer type called "siint".
The "mode" attribute is parameterised with one of the following values to
indicate the specific size of integer required:
QI 8-bit
HI 16-bit
SI 32-bit
DI 64-bit
TI 128-bit
