One potential issue is that for strtol such a change would break all callers that pass a const-qualified pointer as first argument and provide an argument for enptr second, which now has to be a pointer to a non-const pointer. For the functions we changed this breaks only cases where a const qualified pointer is passed and then the result is assigned to a non-const pointer, which could already be considered questionable in existing code.
