I seem to remember that you can force the build of gcc to pass the
-fno-exceptions option by default for avr C++ programs.... Ah, yes, here
it is in this patch:
http://freesoftware.fsf.org/download/simulavr/binaries/SOURCES/gcc-3.0.4-patchc++
That should probably be put into the gcc cvs tree. Attached is the patch
for gcc. Joerg, try it and see if the results are what you expect without
the -fno-exceptions option.
