Thanks to all who responded, by email, here, and otherwise. The problem is that
the original K&R specified that all float arguments be promoted to double. To
avoid this promotion, you need to have funtion prototypes. Furthermore, the
prototypes have to be in the following format -

In files that will be using the extern function, you need something like this -

void far fnPlotSegment (int, float, float);

In the module that contains the function, you must have -

void FAR fnPlotSegment (int myVar1, float myVar2, float myVar3) 
{...
}

Note that the following will _not_ work -
void FAR fnPlotSegment (myVar1, myVar2, myVar3)
int myVar1;
float myVar2;
float myVar3;
{...
}

Once again thank you for clarifying this point.
