I think that AVR macro goes away with some of the options, probably at
least with -ansi.  Then only the implementation namespace macros will

Note that the preprocessor info pages contain documentation for the
predefined macros.  If you're on Unix, type "info cpp", then go to the
"Macros" and "Predefined Macros" nodes.  They are lacking exact
documentation on the system-specific (i.e. AVR-specific in our case)
macros, but you'll find documentation for them in the avr-libc docs.
If something is missing in the latter, please file a bug report.
