Re: [avr-libc-dev] does delay.h really need all this junk?

After all, the convenience of using F_CPU and times in microseconds
and milliseconds is *the* difference between _delay_us and _delay_ms,
vs. just using _delay_loop_1 and _delay_loop_2 directly.  The latter
have been there well before, and the functionality to specify the
delay in a more natural (to humans) way once used to be a frequently
requested item.

Btw., _delay_ms now falls back to a wrapped outer/inner loop approach
iff the delay gets too large, since there have obviously been too many
people trying to call _delay_ms(500) or such.
