It's not gcc to support "z" (except for the compile-time check); it's the C library (on Unix, the C library is part of the system, not part of the compiler). But yes: if we could detect in configure that the C library supports %zd, then we should use that.

I created patch 1474907 with a fix for it. Checks if %zd works for size_t and if so sets PY_FORMAT_SIZE_T to "z", otherwise just doesn't set the macro def.

Assigned to Martin to make sure I didn't foul it up, but pretty much anyone could probably double-check it.
