 * Name: wcscoll
 *
 * Description:
 *   The wcscoll() compares the wide-character string pointed to by a to the
 *   wide-character string pointed to by b using an interpretation appropriate
 *   to the current LC_COLLATE state.
 *
 *   The current implementation of wcscoll() simply uses wcscmp() and does
 *   not support any language-specific sorting.
