Doing this as cleanly as possible involved demoting several function parameters concerning object sizes and counts from size_t to int--I'm fine with this change as the functions in question are not actually capable of handling input with sizes larger than what can be stored in a signed 32-bit integer, making the use of size_t here misleading at best.
