Can you provide a complete linker command line (please add -v
to the compiler options), and even better, sample source code
to reproduce the issue?

In a quick, I cannot reproduce it using the following source
code:

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

int
main(void)
{
        double f;

        f = atof("3.1415926");
        return (int)f;
}

regardless of whether I specify -lm or not.
