What do you need to change there?  Normally, they are designed in a
way to allow full customization without touching the source code.

The file is named gcrt1.S, and is the same source file for all
processors, using conditional compilation.  It is part of avr-libc.
The download URL etc. should be contained in WinAVR's accompanying
documentation.

AFAICT, the latest WinAVR has applied a patch to it for the new
controller devices.  That patch is part of WinAVR (and should be right
there, on your disk).

That's the question I'd like to ask *you* -- because I simply don't
know what you're going to change there at all.

I'm afraid you simply didn't understand how avr-libc's interrupt
vector dispatcher works...  Please try reading the documentation first
(again, on your disk -- but you probably guessed that already ;-).
