Misc updates for CPP-DEFINES

parent 6edd2f3d
Here are some of the cpp macros used, together with some short explanation
of their use. Feel free to add more macros and more categories.
Most of these are from config.in, so it's probably better to put the
explanations in that file. Ideally, everything would be defined and
documented in config.in, and this file would not be necessary.
