These annoying warnings from the C compiler result from the code
that the compiler generates for semidet `pragma c_code'.
You can safely ignore them.

This minor annoyance has been around for a while.  I think the reason
that they arise with this example for the release-of-the-day compiler
but not for 0.8 is just that the rotd compiler does a better job of
intermodule optimization, inlining the `pragma c_code' from the Mercury
standard library into the C code that it generates for your module.
