* Add new conversions functions for PyLong: - PyLong_FromIntMax() - PyLong_FromUIntMax() - PyLong_AsIntMax() - PyLong_AsIntMaxAndOverflow() - PyLong_AsUIntMax() * getargs: add 'm' format * New _testcapi constants: INTMAX_MAX, INTMAX_MIN, UINTMAX_MAX, SIZEOF_INTMAX_T * Add _testcapi.getargs_m() and _testcapi.test_long_intmax_api() * PyLong_FromVoidPtr() uses PyLong_FromUIntMax() * Use intmax_t in various modules array, struct, ctypes and memoryview are not modified yet to support intmax_t.

I'm sure 64 bit is enough for all LZMA constants.

size is a 64-bit number. long long is enough.

I think this condition is always true. I think that it is always true even for long long. I added this check only because the support of long long was optional.

Shouldn't be used PyLong_FromUIntMax?

(long)?
Can d_ino be negative?

Add new conversions functions for PyLong:
getargs: add 'm' format
New _testcapi constants: INTMAX_MAX, INTMAX_MIN, UINTMAX_MAX, SIZEOF_INTMAX_T
Add _testcapi.getargs_m() and _testcapi.test_long_intmax_api()
PyLong_FromVoidPtr() uses PyLong_FromUIntMax()
Use intmax_t in various modules
array, struct, ctypes and memoryview are not modified yet to support
intmax_t.
