/WARN=( ENABLE=( NOC99, OBSOLESCENT, DEFUNCT, QUESTCODE, ...), DISABLE=(...))

Adding VERBOSE and OVERFLOW can be useful.

#pragma environment save and restore around #pragma message disable 
cases where compilations errors are expected and cannot otherwise be 
eliminated. Preferably with explanatory doc.

I typically don't bother upgrading warnings and such to errors or fatal 
(which is ~possible on OpenVMS), choosing to not transfer code that 
doesn't compile cleanly with the above switches into production.

Moving to these diagnostic, and removing home-grown memory management 
schemes and some other steps, has resolved a number of subtle errors in 
large and complex systems.

So too has been fully-integrated logging and debugging support within 
large and complex apps, rather than treating all that as an 
afterthought. This being as important as the compiler switches.
