It would certainly be easier for the large fraction of the world who
aren't called Michael if it was spelled like that, but it ain't.  It
is remarkable just how often people do that though.

Heh, well I'm taking enough drugs to cope with my wisdom teeth today
you're lucky if I make sense never mind spell things right.

I was clearly being optimistic here :-/

I thought the problem with DL_IMPORT/DL_EXPORT was that you wanted one
when statically linking and the other when dynamically linking.  But I
could be wrong.  pyapicompat.h could presumably import more or less
verbatim the whole preprocessory mess that defines PyAPI_FUNC in
Python today? AFAIK it doesn't depend on anything else from Python or
autoconf or so on.  Maybe.
