Cygwin isn't a supported platform for MIT krb5, and I think it would
take a fair amount of work, or at least expertise, to get a cygwin build
working.  We don't really support a static library build; I added the
partial support for --disable-shared --enable-static back when gcov
didn't work with shared libraries, and haven't maintained it.

I'm not sure where this is coming from.  Our Windows build currently
requires MSVC 2010.  Getting it to work with later versions might not
require too many changes.
