[gc@obiwan ~] echo -e '#include <math.h>\nint main() { printf("sin 0.5 gives %f\\n",
sin(0.5)); }' > t.c
[gc@obiwan ~] gcc t.c -lm
[gc@obiwan ~] ./a.out
sin 0.5 gives 0.479426
[gc@obiwan ~]
You're probably just grepping out <math.h>. Don't forget that a header
file may include other header file(s).
