Nope!  Even if you get a warning about binary API mismatch across releases,
it's *just* a warning -- the extension is very likely to run correctly
despite it.  For example, the binary API got bumped for 2.1 because new
parameters were added to PyCode_New() and PyFrame_New(), but few extensions
have a reason to use those functions.
