OK, seems like LUABIND_NO_ERROR_CHECKING is broken in 0.9. The problem
is that we have code like:

  # ifndef LUABIND_NO_ERROR_CHECKING
      if (converter.match(...) == -1)
      {
          // ... report failure
      }
  # endif

      ... converter.apply(...); // do actual conversion

This was fine in 0.8, but in 0.9 the conversion process has two stages,
the first being match(), so they have to be called in succession.

I suggest turning off LUABIND_NO_ERROR_CHECKING; it doesn't do very much
 in 0.9 anyway.
