Here is something I've just noticed in using the atof() library routine in
Turbo C 2.0. When the following test program is compiled with the "-DWEIRD"
option, the correct answer is printed. However, when "WEIRD" is not
#defined, the error message "scanf : floating point formats not linked" is
printed at runtime. Does the compilation of the sscanf() load in some other
code needed for atof()? If so, how do I get this code loaded without the
dummy call to sscanf() (which in the example is never executed).

Thanks,

	char s[10];
	double a;
	int yuck;

	sprintf(s," 1.00");

#ifdef WEIRD
	yuck = 0;
	if(yuck == 1)
		sscanf(s, "%f", &a);
#endif
	a = atof(s);
	printf("%f\n", a);
