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.
