Normally DB-Library sets the hostname by default, but it may not do so
on a Win32 platform (if that's what you are using).
There is a DBSETLHOST(loginrec, hostname) call, but Sybase::DBlib
doesn't implement it (or at least not yet).
You could add the hostname to the appname field (i.e. "db_app on
$host", or something like that).
Or add this to DBlib.xs and call before making a connection:
char * host
Put this around line 4540 of DBlib.xs (where you also have the
definitions of DBSETLCHARSET, etc), rebuild, and then call with
