Thanks for the pointer... must find my SYS$ and LIB$ references ...
they've been stolen. Unfortunately my VAX VMS V6.2 + DEC C 5.3 copy of
lib$routines.h has this vague prototype:
$ sea lib$routines.h ediv
/* LIB$EDIV */
/* LIB$EDIV makes the VAX EDIV */
unsigned int lib$ediv(__unknown_params);
So this does indeed look promising...
