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:
