What GCC version had <stdint.h> defined?

Well, currently pyconfig.h for 2.4 says:
     ...
     #if _MSC_VER != 1200
     #define HAVE_UINTPTR_T 1
     #define HAVE_INTPTR_T 1
     #endif
     ...

which is actually a pretty low bar to get over.

I'd like to change it to something like:
     ...
     #if _MSC_VER > 1200
     #define HAVE_UINTPTR_T 1
     #define HAVE_INTPTR_T 1
     #endif
     ...
     #if GCC_VERSION >= 30100
     #define HAVE_UINTPTR_T 1
     #define HAVE_INTPTR_T 1
     #endif
     ...

which is arguably better even if not good enough.
Is there a better test I can do at compile time?
