Details:

I'm getting a linking error ( below ) using g++ 3.4.3 with an ATMega168.

I can make the source compile or not compile by commenting out a line
equivalent to 'f+=10.0' where f is a float.

The linker version is 2.15.
..
switching back to gcc ( from g++ ) shrinks the code dramatically ( much more
than the usual g++/gcc difference ) and the problem goes away.  Don't know if
it will reappear as I reach the memory limits.
