All extensions are supposed to be properly protected (either by
marking them as __extension__, or by using the double-underlined
versions of keywords, as __asm__), so I think "-pedantic"-safety
should really be a goal of avr-libc.

I agree that we might only want to maintain warning-free compilation
for -std=c99 or -std=gnu99.  There are pieces of code already that
don't even work without it (like, <util/atomic.h>).  If it still works
with -std=c89 or -std=gnu89 (which is currently still GCC's default),
it's fine, if it doesn't, we don't care much.

After all, the current ISO C standard did pass its 10th birthday
already, so it's already a teenager now. ;-)
