I have tested this: The one that is specified last on the command line 
takes effect:

int main()
{
     return 0;
     return 0;    // Warning: statement is not reachable
}

$ dmd deneme.d        # compiles without any diagnostics

$ dmd deneme.d -w     # breaks compilation
$ dmd deneme.d -wi -w # ditto

$ dmd deneme.d -wi    # warns but compiles
$ dmd deneme.d -w -wi # ditto
