Fixed warnings on AMD64, thanks to Mooie <mooie@cow.se> for the patch.

* plugins.d/askpass-fifo.c (main): Cast value from TEMP_FAILURE_RETRY
                                   to int, the value the inner
                                   function returns.
* plugins.d/mandos-client.c (init_gpgme): - '' -
  (start_mandos_communication): New variable "ssize_t sret"; used to
                                store return value from
                                "gnutls_record_recv".  Also cast value
                                from TEMP_FAILURE_RETRY as above.

Lines of Context:

The Mandos server announces itself as a Zeroconf service of type
2
 
"_mandos._tcp". The Mandos client sends a line of text where the first
3
 
whitespace-separated field is the protocol version, which currently is
4
 
"1".  The client and server then start a TLS protocol handshake with a
5
 
slight quirk: the Mandos server program acts as a TLS "client" while
6
 
the connecting Mandos client acts as a TLS "server".  The Mandos
7
 
client must supply an OpenPGP certificate, and the fingerprint of this
8
 
certificate is used by the Mandos server to look up (in a list read
9
 
from a file at start time) which binary blob to give the client.  No
10
 
other authentication or authorization is done by the server.
