mingw: disallow compile warnings during the build

dscho · dscho · commit b4c390e17563 · 2017-10-02T17:33:40.000+02:00
More than once, in this developer's past ignoring a compile warning
resulted in multiple days of bug hunting, just to find out that the
warning actually pointed to a serious problem like, say, an erroneous
64-bit -&gt; 32-bit case (losing crucial information).

So let's just not ignore those warnings but make them fatal instead.
