Yes.  I putzed with this more last night and since I 
couldn't find them, it looked like avr-libc, but thanks for 
confirming that.  Slowly we learn more about the nuts and

Running Gentoo Linux, updated daily :).  Tool versions are 
as follows:

*  dev-embedded/avr-binutils
      Latest version available: 2.15
      Latest version installed: 2.15
      Size of downloaded files: 11,245 kB

*  dev-embedded/avr-gcc
      Latest version available: 3.4.3
      Latest version installed: 3.4.3
      Size of downloaded files: 26,782 kB

*  dev-embedded/avr-libc
      Latest version available: 1.2.1
      Latest version installed: 1.2.1
      Size of downloaded files: 311 kB

Both binutils and gcc are patched as is, in theory,

downgraded that back to 3.4.3.

So far, all seems well for the Mega8L, Mega32L and the
