The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: added more trivial lexical helper macros so that uses of these guys expand to nothing at all when they're not enabled. This should help sub- standard compilers that can't do a good job of optimizing away the previous "(void)0" expressions. Py_DECREF: There's only one definition of this now. Yay! That was that last one in the family defined multiple times in an #ifdef maze. Py_FatalError(): Changed the char* signature to const char*. _Py_NegativeRefcount(): New helper function for the Py_REF_DEBUG expansion of Py_DECREF. Calling an external function cuts down on the volume of generated code. The previous inline expansion of abort() didn't work as intended on Windows (the program often kept going, and the error msg scrolled off the screen unseen). _Py_NegativeRefcount calls Py_FatalError instead, which captures our best knowledge of how to abort effectively across platforms.
