problem with ld that comes with version 2.10.0.24

I just installed binutils yesterday, and since then almost all programs
won't compile, I tried to compile this simple hello world program:

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

int main(void) {
        double x, y ,z ;

        x = 4.5; y = 5.8;
        printf("hello world\n");
        z = pow(x,y);
}

and I got this error message : 

[root on /home/root]#gcc -lm hello.c
/usr/lib/crt1.o: In function `_start':
/usr/lib/crt1.o(.text+0x1d): undefined reference to `__libc_start_main'
collect2: ld returned 1 exit status
[root on /home/root]#

what has caused this problem ?
I am using gcc version 2.95.1, & glibc version 2.1.3
