  *Purpose:
  *	defines _wcsdup() - grab new memory, and duplicate the string into it
  *	(wide-character).
  *
  *Revision History:
  *	09-09-91  ETC	Created from strdup.c.
  *	04-07-92  KRS	Updated and ripped out _INTL switches.

  *wchar_t *_wcsdup(string) - duplicate string into malloc'd memory
  *
  *Purpose:
  *	Allocates enough storage via malloc() for a copy of the
  *	string, copies the string into the new memory, and returns
  *	a pointer to it (wide-character).
  *
  *Entry:
  *	wchar_t *string - string to copy into new memory
  *
  *Exit:
  *	returns a pointer to the newly allocated storage with the
  *	string in it.
  *
  *	returns NULL if enough memory could not be allocated, or
  *	string was NULL.
