I think this might be problem on our own end, actually. The distutils.sysconfig code did a = '-I' + distutils.sysconfig.get_python_inc(False) b = '-I' + distutils.sysconfig.get_python_inc(True) which the patch upthread changed to +a = '-I' + sysconfig.get_path('include') +b = '-I' + sysconfig.get_path('platinclude') but I think that's possibly not quite the right translation? The recommended way to find flags to compile against python appears to be the python$version-config binary. To which we might not want to switch. But even so, it seems using sysconfig.get_config_vars('INCLUDEPY') or such seems like it might be a better translation than the above sysconfig.get_path() stuff? For me that returns more sensible paths. Greetings, Andres Freund
