LOL, I'm gonna hold out for a COBOL port for the avr, God 
knows I'd be embarrased to admit how much of that I have 
written over the years (and would indeed prefer to forget 
it :-).

This is all good and fine, but it still doesn't change the 
fact that there are PILES out existing code out there that 
use it.

Yep, it is a problem, no question about it.

IIRC, when I first discovered the avr-gcc toolchain (it was 
a *HAPPY DANCE* day :-), I had a problem finding docs for 
it, I don't remember exactly why now, something about some 
site I could never get to comes to mind ?!??  Also not 
helping was that the gentoo ebuilds were so old.  This is 
why I am working at trying to help get it to be and stay 
current.  Up until I got involved in this, my toolchain was 
(still on the backup box):
