[New-bugs-announce] [issue46816] Remove declarations for non-__STDC__ compilers

[Oleg Iarygin]

New submission from Oleg Iarygin <oleg at arhadthedev.net>:

Currently, Python code contains two places where presence of __STDC__ is checked:

- Include/internal/pycore_pymath.h:12
- Python/errors.c:13

These checks are used to add extern functions missing in non-standard versions of math.h.

However, after Python switched to C99, there is a guarantee that every compiler conforms to ISO C so checks of __STDC__ have no sense anymore.

Note, that:

- errors.c check was added by 53e8d44 on 9 Mar 1995
- pycore_pymath.h check was initially added into Objects/floatobject.c by eddc144 on 20 Nov 2003 then moved to pycore_pymath by 53876d9.
