G++ switch to make everything public in a class?

[Jeffrey Walton]

Hi All,

I'm interested in writing test cases against c++ classes. For testing,
I'd like everything to be public so I can call protected and private
functions with bad data for negative test cases.

I don't want to use friendship since its for testing only (it would
pollute the interfaces).

Is there a switch to force everything public? If not, how does one
typically access the non-public stuff for testing?
