Can we see the first 50 lines of your code?

      1 #include <stdlib.h>
      2 #include <stdio.h>
      3
      4 int main() {
      5         printf("%ld\n", random());
      6         return 0;
      7 }

gcc -c -O3 -Wall -pedantic test.c

works fine here with no errors or warnings.

$ gcc --version
gcc (GCC) 4.0.1 20050727 (Red Hat 4.0.1-5)

Is your $INCLUDE set in your shell and you pick up a different stdlib.h?
