The compiler is supposed to catch errors like these with -dip1000.
Recently there was a DIP1000-related fix checked in that fixed some of
the problems with -dip1000 (specifically, a linker error I was running
into), so you may want to consider compiling with -dip1000 if you're
running the latest compiler.
