--- Comment #7 from Kaz Kylheku <kkylheku at gmail dot com> --- Also, it would be useful for the documentation to list all the -W-* options that are implied by -Wpedantic. The function/object pointer conversion diagnostics, unfortunately, are tied to -Wpedantic itself, which is unhelpful. -Wpedantic serves both as a diagnostic option, and a container for diagnostic options. E.g if you don't want the extension of void * pointer arithmetic, you can use -Wpointer-arith to diagnose it; that is turned on by -Wpedantic.
