I discover patch for gpgme in gpg4win source. (patches/gpgme/01-gpg2.patch)
Claws-mail uses libgpgme-11.dll in gpg4win binary, which includes string
'gpg2.exe'.
I recognize gpgme in gpg4win is official version (on Windows).
We will use this version. Thank you.
- Claws-mail is based on Sylpheed. but, it doesn't work my environment.
