/*
   WISERVIC.H -- New include file by Antti Karttunen 29. May 1997
                 for the new module WISERVIC.C and main module CHIL.C
                 Contains also prototypes and macros (e.g. an auxiliary
                 function like wisvc_handle_W_option) for Unix builds,
                 so do not miss this module from them.

    4.June.1997 AK  Changed the prototype of wisvc_send_wait_hint
