---------------------------------+------------------------------------------
 Enabling GhcDynamic causes the Windows build to fail:

 {{{

 -iutils/ghctags/dist-install/build -iutils/ghctags/dist-

 error while loading shared libraries:
 libHSprocess-1.0.1.4-ghc7.1.20110630.dll: cannot open shared object file:
 No such file or directory
 }}}

 The reason is that Windows searches for DLLs in the application directory,
 and the DLLs that a dynamic GHC depends on are not placed in that
 directory. (See http://msdn.microsoft.com/en-
 us/library/ms682586(v=vs.85).aspx)

 Presumably the fix is to have the build system copy the dependent DLLs
 into inplace/bin as the final act of the stage2 build.  (I'm not sure what
 happens after GHC is installed - presumably the DLLs are put into System32
 or something?)
