Hello Pythonistas.
In (development branch of) Fedora, we have juts upgraded to GCC 12.
It seems that the presence of AC_C_CHAR_UNSIGNED in Python's autotools files
(configure.ac?) is causing the __CHAR_UNSIGNED__ symbol to be defined in
pyconfig.h and that breaks some other packages with GCC 12.
The GCC maintainers told us it is a reserved symbol,
see https://bugzilla.redhat.com/2043555 for details.
It seems that using AC_C_CHAR_UNSIGNED is not recommended and also not
required, but I must confess that I am pretty much horrified by autotools and I
don't really know if we can get rid of AC_C_CHAR_UNSIGNED or not. I can test
this in Fedora and I am quite sure it'll work, but I don't know the impact on
all the other environments where CPython can be compiled.
Is there anybody on this list who knows a reason we need to keep
AC_C_CHAR_UNSIGNED around in 2022? Or is it safe to get rid of it?
Thanks,
