Looking at the code for get_python_inc() in 2.7, it seems that plat_specific
toggles between CONFINCLUDEPY and INCLUDEPY. Except on windows, where it uses
get_path('include') for both. sysconfig.py sets INCLUDEPY to
get_path('include') on windows, so we'd be good with INCLUDEPY there.

Maybe something like the attached? Not particularly nice, but should give us
most of the relevant information?
