16  * Fundamental character types.
17  *
18  * CHAR_T	An integral type that can hold any character.
19  * ARG_CHAR_T	The type of a CHAR_T when passed as an argument using
20  *		traditional promotion rules.  It should also be able
21  *		to be compared against any CHAR_T for equality without
22  *		problems.
23  * UCHAR_T	The shortest unified character type (8-bit clean).
24  * RCHAR_T	The character type used by the internal regex engine.
25  *
26  * If no integral type can hold a character, don't even try the port.
