[Bug c/28876] New: Provide -W options for all warnings enabled by -Wextra


There are some really useful warnings enabled by -Wextra that don't have
separate -W enablers.  They should, as not everyone likes all the noise that
-Wextra generates.

These two are the ones I failed to find how to enable other than by using
-Wextra:

warning: comparison of unsigned expression >= 0 is always true
warning: variable 'status' might be clobbered by 'longjmp' or 'vfork'
