The C++ spec does not talk about errors and warnings. Instead, it
requires that an implementation should produce *diagnostic
message*. It is implementation-defined what constitutes these
diagnostics. For g++, diagnostics include error and warning message.

As Jason points out, -pedantic-errors turns warnings into errors.
