* agent/call-scd.c (start_scd): Replace int by assuan_fd_t. (start_pinentry): Ditto. * common/asshelp.c (start_new_gpg_agent): Replace int by assuan_fd_t. * common/dotlock.c (GNUPG_MAJOR_VERSION): Include stringhelp.h for prototypes on Windows and some other platforms. * common/logging.c (fun_writer): Declare addrbuf only if needed. * g10/decrypt.c (decrypt_message_fd) [W32]: Return not_implemented. * g10/encrypt.c (encrypt_crypt) [W32]: Return error if used in server mode. * g10/dearmor.c (dearmor_file, enarmor_file): Replace GNUPG_INVALID_FD by -1 as temporary hack for Windows. * g10/export.c (do_export): Ditto. * g10/revoke.c (gen_desig_revoke, gen_revoke): Ditto. * g10/sign.c (sign_file, clearsign_file, sign_symencrypt_file): Ditto. * g10/server.c (cmd_verify, gpg_server) [W32]: Return an error. -- The gpg server mode is not actual working and thus we can avoid the warnings by explicitly disabling the mode. We keep it working under Unix, though.
