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.
