For small targets like this, it is common to compile C++ with "-fno-rtti
-fno-exceptions", as these features can have a lot of overhead and need
library support, and are seldom useful on such targets.  For the AVR
port of gcc, C++ works with these flags.  So if you are able to say "C++
works with exceptions and rtti disabled" then that would be fantastic -
the final parts may be nice to get completed, but I don't think they are
a priority to users.

(That's my 2 øre, anyway.)
