The ISO C strncpy is required to always write exactly n chars into the destination (null characters are appended). This fact is not nearly well enough known. Presumably you know for sure, but I doubt that Lua relies on this null padding.
Also, many of the prototypes are not C99 compliant, but that is really the standard's fault, not yours.
