39  * the lfs module and lua's base code. We define them minimally here so we don't
40  * have to modify lua on every import. Further, since they aren't completely
41  * standard, we #define them to other names so they don't conflict with other
42  * tooling that makes assumptions about these routines that might not be, in
43  * fact, correct.
