Hmm, that's right. But the EOPNOTSUPP comes from data.c, which holds
generic, platform independent mappings to the platform specific code,
if I see this right.
The question here seems to be: Can we assume EOPNOTSUPP do be more or
less platform-independent or not? In other  words: which standard
(POSIX?) defines the existense of this constant?
Or should we use one of the other error conditions, as I suggested in my
last mail to this list?

Despite a few simple modifications (which are mostly not mingw-specific)
gpgme compiles well with actual mingw versions from mingw.org, gnupg (at
least 1.2.1) compiles out of the box.
After testing, I will post a patch.
