Details:


I tried building avr-libc-1.7.0 from the source-tarball, according to the
instructions found at at
  http://www.nongnu.org/avr-libc/user-manual/install_tools.html
and 
  http://www.mbeckler.org/microcontrollers/avrgcc_build/.


Executing:
./configure --prefix=/usr/local/avr --build=`./config.guess` --host=avr

... succeeds, but compiling fails in directory
       /avr/lib/avr25/attiny2313a
complaining with:
       warning: #warning "device type not defined"


On inspection of config.log I see that the configure script failed to detect,
that the following MCUs are not supported by my avr-gcc compiler:
 attiny2313a 
 attiny24a 
 attiny261a
 attiny4313
 attiny44a
It flags those as being supported, which is not the case.
Other unsupported MCUs are detected correctly.

See attached config.log for details.

The avr-gcc I am using was also compiled from the original source-tarball of
the 4.5.0 release.
