Hello Daniel,

Thank you for the reply.

I now see the output I was expecting, I think if I pass -de and -02 (or 
anything else it requires like -fssa) a warning that nothing will happen 
should be printed to stderr about the args I passed.  Do you agree?

Could anyone tell me if there is a bug db online for gcc similar to 
bugzilla?

Regards

JG

please cc me in any replies
