I found the following in this file. This looks as if everything should stay as it is.

/* Note for Windows: Ignore the incompatible pointer type warning for

   int64_t while mingw uses __int64_t.  It does not matter at all
   because under Windows long and int are both 32 bit even on 64
   bit.  */

gpgme_ssize_t is even documented in gpgme.texi.

Cast instead of using FARPROC

The compile error:

I don't think we need a fallback. For the group configuration we can manually look in the old location. And for everything else it's okay to lose the configuration.
