The standard does not mandate warning.  It mandates diagnostics.
We (GNU C++) have chosed to classify some of them as just warning
instead of hard errors -- also known as pedwarn.

-pedantic usally means adherence to the letter of the standard.  So,
I'm inclined NOT to introduce yet another knob for this.  People are
routinely asking the compiler to be more compliant; it is the least to
expect that, in return, they are willing to adhere to the standard :-)
