Contact Marek Michalkiewicz marekm@amelek.gda.pl regarding avr-libc as he 
is the maintainer.  The site below is the official source for avr-libc and 
uisp, note there is also an avr patch for gdb5.0

See Ted Roth's troth@verinet.com simulavr 
http://res099095.halls.colostate.edu/programs/simulavr , note he is also 
looking for some help with fixing up some problems with the current gdb5.0
