That version is probably too old to really support C++.

Full C++ support has been added in recent versions of avr-libc, which
requires a current (3.3) version of gcc.  Older versions of avr-libc
didn't call global/static constructors/destructors.

Normally, gcc detects C++ files by the file extension (.cpp, .cc, or
.C on Unix systems with case-sensitive file systems), and takes the
appropriate actions.

Since there's no libstdc++ for avr-gcc, you have a number of
restrictions that are explained in the FAQ.  See
