[avr-libc-dev] Why is iom88p.h so different from iomx8.h? (mega88->mega88P)

[Tod E. Kurt]

Hi,

I'm migrating several designs from ATmega88- to ATmega88P-class of  
MCUs and I'm finding lots of small frustrating changes that I can't  
find a reason for.

The two main differences I've been bitten by are:
- No "PB3"-style pin names, only "PORTB3"-style
- No "SIG_INTERRUPT0"-style interrupt vectors, only "INT0_vect"-style

Is this a bug or an intentional change?  If it's intentional, what is  
the rationale?

It looks like the interrupt name problem causes the V-USB library to  
fail silently (avr-as not doing checks on .globals?)

Thanks everyone who's worked on AVR-GCC.  It is a wonderful tool.
