Details:

On avr-chat, a user noted that certain macros (apparently including PSTR()
and pgm_read_byte()) would give warnings under "-ansi -pedantic".

Adding __extension__ to these macros in avr-libc header files will allow the
macros to be used without triggering warnins with these flags.

Example:
#define PSTR(s) (__extension__({static char __c[] PROGMEM = (s); __c;}))
