+ * camel-tcp-stream-openssl.c (ssl_error_to_errno): New function. Try
+ to approximate the SSL error into errno.
+ (errlib_error_to_errno): New function, try to approximate OpenSSl's
+ error library's error (ERR_*) into errno.
+ (stream_read): Try to set errno using ssl_error_to_errno.
+ (stream_write): Same.
+ (open_ssl_connection): Same.
+
* providers/imap/camel-imap-store.c (imap_connect_online): Oh crap,
huge killer typo.
