By default g++ does have exception handling enabled.  You can turn it 
off with -fno-exception (sp?).

If you are integrating legacy C or assembly code, you have to arrange it 
so that the exception tables are generated.  Use -fexception 
-fnon-call-exceptions I think for gcc.  For assembly things get much 
more complicated (look at the libffi source for examples).
