Then rather than play with true division now, you'll have a lot more fun
rewriting that in 9 lines of Python; C++/Python ratios of a million are
common for experienced Python programmers, but as a beginner don't feel bad
if you only get a factor of 100,000 savings.  By the way, you should become
a PSF sponsor too, and especially if you believed that <wink>.

If you're trying to get the effect of passing -Qwarn to a standalone Python,
yes, that's all you need to do.  And #include'ing Python.h is all you need
to do to get at all names in Python's C API (Py_DivisionWarningFlag among
them).  Have fun!
