Here is a list of the macro names that have changed.
As you can see, most of these are anyway undocumented,
and you probably never knew they existed.
Also changed, but not listed here, are the macros used
to prevent double inclusion of ".h" files.

Also, the identifiers like INIT_VAL, INIT_SIZE, INIT_FFT
are no longer macros, but are defined to be constant objects
of particular classes.  Their names do not change.
