Comment:
Removing `libstdc++.dll.a` sounds like the wrong thing to me.
There's no technical reason why we need to include the C++ support at all,
but we do so to make it easier for Windows people who want to link with
C++ code. I think there are two options that make sense:
* Add `libstdc++-6.dll` so dynamically linked C++ programs work, although
presumably you'll have to either change your path or put the DLL in the
right place. If you want a statically linked program then you need to use
`-optl-static` as normal.
* Remove the C++ bits that we currently do include. Users who want C++
support will need install more mingw bits themselves, either as part of
the GHC in-tree mingw, or as part of a normal system mingw installation.
Any thoughts?
