2003-04-10  Nick Garnett  

        * src/mn10300_am33.ld:

        Added .eh_frame to data section. This is a stopgap fix to allow

        C++ programs that define exceptions to link and run. It does not

        allow them to actually throw exceptions, since that depends on

        compiler changes that have not been made. Further, more

        far-reaching, linker script changes will also be needs when that

        happens.

        Added libsupc++.a to GROUP() directive for GCC versions later than

        3.0.
