Re: [avr-libc-dev] [bug #38765] avr/iotnx5.h defines USI_OFL_vect not US

Unfortunately savannah will not let me register, keeps complaining that
I should contact its administrator.

Is there any way to complain to Atmel and suggest that a little 
consistancy would be helpful.  Otherwise code just becomes a mess
of #if trees.

As an alternative, as so as not to break existing code, would it not
be possible to define both, i.e. if OVF is defined then define OVERFLOW
to match, and vica verca.
