A lot depends on the environment/architecture.

Compiling on VMS in the system I inherited, there were numerous warnings 
that could not be suppressed. I did spend a _lot_ of time removing 
others - no code I wrote had direct warnings.

Likewise in various other environments.

Otherwise in principle I would agree with you
