AssertionError: fmod(-10, 1): expected -0.0, got 0.0 (zero has wrong sign)
Here Windows loose sign of the result; if y is nonzero, the result
should have the same sign as x.
This amends commit 28aea5d07d.
Use a `_PyStackRef` and defer the reference to `f_executable` when
possible. This avoids some reference count contention in the common case
of executing the same code object from multiple threads concurrently in
the free-threaded build.
POSIX allows errno to be negative.
Even though all currently supported platforms have non-negative errno,
relying on a quirk like that would make Python less portable.
* Raise PicklingError instead of UnicodeEncodeError, ValueError
and AttributeError in both implementations.
* Chain the original exception to the pickle-specific one as __context__.
* Include the error message of ImportError and some AttributeError in
the PicklingError error message.
* Unify error messages between Python and C implementations.
* Refer to documented __reduce__ and __newobj__ callables instead of
internal methods (e.g. save_reduce()) or pickle opcodes (e.g. NEWOBJ).
* Include more details in error messages (what expected, what got).
* Avoid including a potentially long repr of an arbitrary object in
error messages.
* protect macros expansion via `do { ... } while (0)` constructions in `_decimal.c`
* Use public macro `Py_UNUSED`
This replaces the usages of the `UNUSED` macro which
was not consistent with the `Py_UNUSED` macro itself.
In addition, this amends the parameter names so that
they match their semantic meanings.
* Remove redundant `PyCFunction` casts
Add PyConfig_Get(), PyConfig_GetInt(), PyConfig_Set() and
PyConfig_Names() functions to get and set the current runtime Python
configuration.
Add visibility and "sys spec" to config and preconfig specifications.
_PyConfig_AsDict() now converts PyConfig.xoptions as a dictionary.

Switch more _Py_IsImmortal(...) assertions to _Py_IsImmortalLoose(...)
The remaining calls to _Py_IsImmortal are in free-threaded-only code,
initialization of core objects, tests, and guards that fall back to
code that works with mortal objects.
This checks are redundant in normal circumstances and can only work if
the extension registry was intentionally broken.
* The Python implementation now raises exception for the extension code
with false boolean value.
* Simplify the C code. RuntimeError is now raised in explicit checks.
* Add many tests.
