Ok, sure. But realistically, it's going to be the AVR port developers 
who will be running the testsuite, and they're already familiar with 
avr-libc (I'm excluding the RTEMS folks for this argument). And since 
the AVR hasn't even made the "secondary" platform status :-), it looks 
like it will continue to be this way for a while.

So, from what I gather with that statment, is that using newlib is just 
a convenience; there's nothing inherent in it that is required for 
testing with a simulator?

Yes, I've seen those too.
Hmm, that's what I was hoping to find out, documentation for those types 
of simulators. I've seen SID <http://sources.redhat.com/sid/> and GGEN 
<http://sources.redhat.com/cgen/>, but does anybody know what is 
currently being used to develop those simulators in the sim directory?, 
what should be used?

Thanks
