Warnings generated during a failed avr target build of 4.0 as of today, on a
mac/dwawin-7.6 host which should likely be verified as being harmless, and
then silenced if so. (sending the report just in case the build failure may
be related to one of the more ominous warnings, and for reference: built via
../gcc/configure --target=avr --disable-nls --enable-languages=c )
[ other more target specific warnings/failures noted via another PR ]
