[New-bugs-announce] [issue45895] _Py_Sigset_Converter used without #ifdef HAVE_SIGSET_T check

[Christian Heimes]

New submission from Christian Heimes <lists at cheimes.de>:

posixmodule.c defines _Py_Sigset_Converter() only when feature macro HAVE_SIGSET_T is set. Several use of the function miss the feature macro check and fail on platforms without sigset_t (e.g. wasm).
