I have already explained you that, and you can take my word that you
don't stand a chance using the existing gcrt1.S file.  That's not to
say it could not be done at all, but you'd have to start over from
scratch, writing your own C run-time startup code in a different way
than the existing code is done.

You could perhaps seek up some old (maybe about 4 years old)
suggestion from Marek Michalkiewicz about what changes would be needed
in order to allow for arbitrarily-named interrupt vectors.  Offhand, I
can't tell you though whether it has been discussed here on
avr-gcc-list, or on avr-libc-dev instead.

Never trust an operating system you don't have sources for. ;-)
