Comment:

 This patch solves the problem. The patch is made against 7.6.3 *with* the
 patch
 https://ghc.haskell.org/trac/ghc/attachment/ticket/7134/ghc-7.6.3-w64fix.patch
 applied.

 These two also should apply to HEAD cleanly in order.

 This patch is *especially* important for 64-bit build because it is
 distributed with mingw-w64 gcc compiler, having
 {{{__declspec(dllimport)}}} as part of windows api specs in header files.
 Hence even C/C++ sources built via GHC driver refer to win32 API
 functions, decorated with {{{__imp_}}} prefix.
