I'm not sure what you are doing, but
keep in mind that Euphoria routines, such as poke4(),
deal with data in Euphoria's internal format.
Euphoria integers and C integers are the same,
as long as you are in the range of (roughly) -1 billion
to +1 billion. Outside of this range a Euphoria library 
routine will interpret the number to be a kind of pointer to
a double or a sequence. To pass a 32-bit integer,
outside of the range, you would have to create a pointer
to a double, like what NewDouble() returns, and pass that. 
This is very tricky, not for the faint of heart.

Also, WinMain() causes a lot of necessary stuff to
be initialized. If you skip it, some things won't work right.
