** byfill() is declared in esqllib.h, this is not normally needed by 7.x
** ESQL/C compilations (though if byfill() is missing, there is room to
** think that other functions may be missing too).
** JL 1999-06-29:
** The 7.24 ESQL/C header declares the iec_* functions, but not byfill.
** It has a conditionally defined macro for byfill which invokes memset.
