I agree on all counts <wink>.  A difficulty with preprocessor symbols is
their very low "discoverability"; for example, the current maze takes as
input symbols like Py_ENABLE_SHARED and HAVE_DECLSPEC_DLL, and it's rarely
clear where all those may be defined, or why.  I got as far as noting that
the current version of PC/pyconfig.h defines HAVE_DECLSPEC_DLL, and may
define Py_ENABLE_SHARED if Py_NO_ENABLE_SHARED isn't defined, ..., and then
the flu convinced me it's time for another nap.
