c_config: Avoid warnings/errors when checking for C functions 

The check for C functions fails with '-Werror' in GCC (5.2).

  return (int)p;
         ^
  The cast here triggers this error:
    error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

  p=(void*)(%s);
    ^
  This conversion triggers another error with '-pedantic -Werror':
    error: ISO C forbids conversion of function pointer to object pointer type [-Werror=pedantic]

  This patch fixes both errors.
