No, -w is literally the same as "Treat warnings as errors", which many 
compilers have (esp. C/C++). DMD is just unique in *calling* it "Warnings" 
instead of "Treat warnings as errors".

I always felt (and still do) that that's an overly puritanical view of 
reality. In an ideal world, yes, there should be no need for warnings and 
everything is either right or wrong. Problem is, reality sucks, and there 
are times when it's impratical or unrealistic to cram a bit of grey into 
that binary "right-or-wrong" mold. Hence, warnings.

I consider that a very strong argument *in favor* of warnings having real 
value.

Of course, this isn't to say that there aren't any warnings we should change 
into errors. Mandatory flow-control at the end of a "case:" block is a prime 
example, IMHO.
