Floating Point Formates

[Tim Kuehn]

I'm working on a program and am having a problem with the atof() function.
Every time I run it with a certain option  turned on I get an error: 
scanf : floating point formats not linked.

The following code sample generates the same error. I've RTFM'd and there's 
not a HINT of anything else that should be brought in in terms of declerations,
etc. 

Anybody have any ideas?

-------code sample here-------
#include <stdio.h>
#include <math.h>
#include <conio.h>
 
char arg[10];
main()
{
clrscr;
printf("start \n");
strcpy(arg, "-f3");
printf("%s \n", arg);
printf("%lf \n", atof(&arg[2]));
}
