I have been trying with and without -mno-cygwin just trying to get
anything to work.
If it (mixing msys/mingw and cygwin libraries) is "not encouraged" or
"not supported", then I just won't do it and I'll either start using
Msys for everything or start keeping two copies of the Windows libraries
around.

Here is the output of make if this is helpful.  Shouldn't matter but
some search and replacing was done.
