Hi, I'm getting confusing (but consistent along a lot of different compilers) results out of this testcase:
int main(int argc, char **argv)
{
  double dm = 1.0;
  unsigned int i = 1;
  if (-i*dm != -((double)i)*dm)
    abort();
  return 0;
}

Why does light come always _after_ hitting submit... #)

Sorry for the noise.

Richard.
