Greatly reduce pow() overhead for small exponents.

…6679)

Change the behaviour of `math.pow(0.0, -math.inf)` and `math.pow(-0.0, -math.inf)` to return positive infinity instead of raising `ValueError`. This makes `math.pow` consistent with the built-in `pow` (and the `**` operator) for this particular special case, and brings the `math.pow` special-case handling into compliance with IEEE 754.

In particular, when running with tk8.6.8, as in PSF 3.9.

…ts (GH-24646)

The function uses distutils.text_file.TextFile and therefore
behaves differently than _parse_makefile in sysconfig.

Py_IS_TYPE() no longer uses Py_TYPE() to avoid a compiler warning:
no longer cast "const PyObject*" to "PyObject*".

In an inheritance chain of

  int -> my_int -> final_int

the data type is now final_int (not my_int)

by-value lookups could fail on complex enums, necessitating a check for
__reduce__ and possibly sabotaging the final enum;

by-name lookups should never fail, and sabotaging is no longer necessary
for class-based enum creation.

… same (GH-26649)

This enables, for example, two base Enums to both inherit from `str`, and then both be mixed into the same final Enum:

    class Str1Enum(str, Enum):
        # some behavior here

    class Str2Enum(str, Enum):
        # some more behavior here

    class FinalStrEnum(Str1Enum, Str2Enum):
        # this now works

If ttk.Spinbox is not available (Tk < 8.5.9) use readonly ttk.Combobox.
