OK, I found out what was the problem (although I am still not entirely
sure what exactly was wrong).

In order to make gpgme build with mingw-w64 4.x, I had to remove
mkstemp() definition from w32-util.c, as mingw-w64 provides this
function from 4.0 onwards. But as it turns out, gpgme's mkstemp()
behaves a bit differently from mkstemp() provided by mingw-w64.

My guess is the use of gpg_err_set_errno() in the function.

I resolved it by renaming the customized mkstemp (see attached diff),
and now gpgme builds, and also works. :) Perhaps this change could be
considered for future-proofing gpgme against environments which
provide mkstemp().
