[avr-libc-dev] [HEAD/1.0] fix pow(N,0)

[Joerg Wunsch]

I've committed the attached patch to both, HEAD and the 1.0 branch.
The patch fixes a bug reported on AVRfreaks.net where pow(N,0)
erroneously yielded 0.5 as opposed to 1.0.  This was caused by a typo
in pow.S (clr rA2 instead of clr rA0).

The actual fix is a bit obfuscated by localizing the labels (see bug
#3573) which I needed in order to debug it in GDB.

For the 1.0 branch, I've also updated NEWS with the recent changes.
Given that Eric and Colin are close to releasing a new WinAVR version,
I'd suggest to also roll a 1.0.5 version of avr-libc (in particular
given the rather serious pow(3) bug fixed).  Ted, if you don't have
the time for that but agree in principle, just tell me what I need to
do for it to happen.
