The attribute warning you can get rid of with the below, on both 3.3.5 
and 2.95:

The "gcc: unrecognized option `-shared-libgcc'" you can not eliminate on 
2.95. The option is not known there. On 3.3.5 it should be there. It was 
introduced somewhere in 3.x. 3.2.3 has it.

Nevertheless, calming down the compiler will not help you in terms of 
exception handling. The tests will fail in execution.
