I have just ported my first program which uses Turbo C's graphics to GEM
and the Atari ST.  Everything works except for when I call evnt_timer(). 

I have checked out 3 different sources on the parameter usage and they
all have a different story.  Abacus' GEM Programmer's Reference says
that evnt_timer() takes two 32-bit parameters, which make up a 64-bit
millisecond delay (the first parameter is the low-order 32 bits ...). 
Tim Oren's Profession GEM series column 12 specifies that the
millisecond delay is a 32-bit value passed as 2 16-bit parameters.  The
aesbind.h file that comes with GCC 1.37.1 says there is one 32-bit
parameter.  I have tried all of these and the result is always that my
timer waits a lot longer than I would like (i.e. the machine seems to
lock up).  If I reverse the order of parameters (where there are 2
parameters, of course), there is no delay.  Can anyone help?
