These tests may test format flags that aren't recognized; don't
warn about that.

Many tests (in particular, the complex math tests) define functions
without a previous declaration - don't warn about that either.
(The -Wno-missing-prototypes option is only relevant for C, not
C++.)

Don't warn about unused parameters like argc/argv.

Also don't warn about unused functions in tests.
