 *
 * Modification History :
 * - 0.01a (13/08/98) : Initial release.
 * - 0.02a (25/08/98) : Added section for logging facility and
 *   a function declarations section. Cosmetics.
 * - 0.10a (27/08/98) : Integration of the parser module into the

 *   definitions for gsmdevices.c. Changed 'struct modem_def'
 *   to 'struct gsms_def' and added fields.
 * ++++ Switched to Beta ++++
 * - 0.14b (23/10/98) : Added 'user' member in 'symbols' struct
 *   and defined MAXUIDLEN.
 * - 0.15b (22/11/98) : Added MBCHKINTERVAL define.
 * - 0.16b (13/12/98) : Added member "owner" to struct gsms_def.
 * - 0.17b (06/02/99) : Added support for access control.
 *   Contributed by Philipp Klaus <[e-mail]>.
 * - 0.18b (11/02/99) : Start rewriting of ACL support.
 * - 0.19b (14/02/99) : Declared public functions for new ACL
 *   implementation.
 * - 0.20b (28/06/99) : Added struct mbox_item to be used by
 *   mbcheck() and friends.
 * - 0.21b (29/06/99) : Moved 3 functions to stuff.c and made
 *   them public.
 * - 0.22b (03/07/99) : Added public definition for trim().
 * - 0.23b (11/07/99) : Added mailbox files definitions.
 * - 0.24b (17/08/99) : Added checkpoint file definition for
 *   interaction with the SMS to mail gateway.
 * - 0.25b (18/08/99) : Published mailgws_death().
 * - 0.26b (20/08/99) : Adapted structure after splitting
 *   stuff.c. Mostly cosmetic.
 * - 0.27b (25/08/99) : Added MAXRETRIES define, as well as
 *   version tracking for sms2mailgw.
 * - 0.28b (28/09/99) : Created struct email_msg and inbox_line,
 *   and exported mailbox_run(). Defined DEFAULTDOMAIN.
 * - 0.29b (17/10/99) : Added FIELD_HEADERS definition.
 * - 0.30b (20/10/99) : Added GWUSER definition.
 * - 0.31b (21/10/99) : Added MAILHOST definition. Moved tellsock()
 *   definition to stuff.c.
 * - 0.32b (09/11/99) : Added nicedate() declaration (exported by
 *   stuff.c).
 * - 0.33b (02/12/99) : Changed DEFAULTSMSC to a catch-all
 *   "default" value in order to improve its handling. See
 *   send_sms() in server.y. Added public export of empty_acl_list()
 *   to accessctrl.c (for "aclist" command).
 * - 0.34b (29/02/00) : Changed struct email_msg to replace recepients
 *   fields with linked lists for easier handling by send_mail().
