(Unless you've got shared libraries you should be able to zap tm-avr.h 
as well.)

The above news is really good.  I suspect ``months ago'' all the 
framework you needed may not have been in place.  Perhaphs also have a 
look over the relevant sections of the gdbint.texinfo file - there is 
plenty of oportunity there for improvement.

nice,
