/*
So, this one's a bit weird. Normally, we'd use include guards to make sure
a header is only included once, but the assert macro is supposed to be
redefined each time assert.h is included based on the current status of
NDEBUG, so we instead undefine-redefine assert and that's it. Technically,
it includes stdlib.h and stdio.h every time it's included, but meh. It's fine.
Those have include guards that mean it doesn't matter.
