[Python-Dev] Re: Require a C compiler supporting C99 to build Python 3.11

IMO we need to distinguish the public C API which should be as much compatible as possible, target the oldest C standard, and the Python internals can require a more recent C standard. For example, today maybe it's reasonable to requires C99 for Include/ headers (public .h files) and support C11 for Python internals (private .c files). Victor
