Besides the point below, remember that the actual MinGW is shipped inside the

Debugging symbols are much bigger and extremely space-inefficient with DWARF2.

That's a mistake. The installed package should not have DLLs in the lib
directory. I think Ossi has already pointed this out to the packaging team.
