The trivial one-liner below compiles fine (and runs) for me when I use 
the following compilation command line:

	gcc -Wall -D_USE_LIBM_MATH_H -O -g -o sft sft.c -lm

So please post more details, including the exact command line, the 
version of the compiler, etc.  Also try my program, just to be sure this 
isn't specific to your program.

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int main (int argc, char **argv)
{
  return printf ("%f\n", sinf(atoi(argv[1])));
}
