Christian Heimes	fa26245a1c	bpo-45548: Remove _math.c workarounds for pre-C99 libm (GH-29179) ... The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible ``libm`` and no longer ship with workarounds for missing acosh, asinh, expm1, and log1p functions. The changeset also removes ``_math.c`` and moves the last remaining workaround into ``_math.h``. This simplifies static builds with ``Modules/Setup`` and resolves symbol conflicts.
