this is with the latest master (1a55164)

Am I doing something wrong? (I'm using an old Omni 6.0 checkout from the end of December if that matters)

You need to include some stuff, for this particular error you need to add #include <stdlib.h>

This is a little bit messy, but I think it fixes the errors https://github.com/HashBang173/multirom/commit/f36fb7a371478b1ac58a88ee81dc4931933cff0c
