Nice one Joseph!

Still on the security/gcc side of things, any chance you could whine at
the right people to get -Wconversion fixed?

Currently, this produces a warning:

void somefunc(unsigned int arg);
...
{
  int i = -1;
  somefunc(i); <--- warning due to signed/unsigned conversion
}

This however does not, despite being the same conversion:

{
  int i = -1;
  unsigned int j = i; <--- no warning
}

Cheers
Chris
