The least you could expect them is to explicitly mention *which*
problems they have found, either (and preferrably) as references to
GCC bug reports, or at least, as detailed descriptions about the
problems someone encountered.

Without that, it's just babbling.  FUD.  (Fear, uncertainty, and
doubt.)  I could tell you as well about GCC 4.3.x having ``several
problems'', and by digging through the GCC bug database, I could
probably even found this sentences with some substance. ;-)

Good idea as well.  Johann did a lot of work on the AVR part of GCC
recently, and he also backported all of the more important bug fixes
to GCC 4.6.x.

But: use GCC 4.6.3 rather than 4.6.2, so you benefit from the C++
progmem string bugfix.
