You can view the latest CVS through a web interface. Here's the
avrlibc project on savannah:
http://nongnu.org/projects/avr-libc/
Look under CVS Repository and click on Browse CVS (Sources).
sfr_defs.h is specifically:
http://savannah.gnu.org/cgi-bin/viewcvs/avr-libc/avr-
libc/include/avr/sfr_defs.h
However: AFAIK, VECTOR has changed to _VECTOR and both _VECTOR and
_BV are defined for C language only.
I would ask, though, why you need to write an ISR completely in
assembly. You can write a C function shell and write code with inline-
assembly:
