FYI OPT_Wmissing_braces is an enum constant; it will always be nonzero.

That is what we decided to do.
Note, however, if the logic required to determine if a warning is
warranted is sufficiently complex, *also* checking the variable is
considered an optimization:
if (warn_missing_braces
&& expensive_warning_check())
warning (OPT_Wmissing_braces, "...");
In this case, the warn_missing_braces check is done only to avoid
calling expensive_warning_check() if we know in advance we won't be
needing it.
