99 * POSIX.1-2001 specifies _tolower() and _toupper() to be macros equivalent to
100 * tolower() and toupper() respectively, minus extra checking to ensure that
101 * the argument is a lower or uppercase letter respectively. We've chosen to
102 * implement these macros with the same error checking as tolower() and
103 * toupper() since this doesn't violate the specification itself, only its
104 * intent. We purposely leave _tolower() and _toupper() undocumented to
105 * discourage their use.
107 * XXX isascii() and toascii() should similarly be undocumented.
