From gcc mailing list today: <quote>
All GCC targets (except perhaps some specialized targets for certain DSPs and microcontrollers) support 64-bit integers.
Almost all GCC targets are either "ILP32" or "LP64".
For ILP32: short is 16 bits int, long, pointers are 32 bits "long long" is 64 bits
For LP64: short is 16 bits int is 32 bits long, pointers, and "long long" are 64 bits
None of this requires a specific version, as all these types have been around for a long time. </quote>
