105 * POSIX.1-2001 specifies _tolower() and _toupper() to be macros equivalent to
106 * tolower() and toupper() respectively, minus extra checking to ensure that
107 * the argument is a lower or uppercase letter respectively.  We've chosen to
108 * implement these macros with the same error checking as tolower() and
109 * toupper() since this doesn't violate the specification itself, only its
110 * intent.  We purposely leave _tolower() and _toupper() undocumented to
