32 * You might think that this could be incorporated into regcomp.c, and
33 * that would be a reasonable idea... except that this is a generic
34 * function (with a generic name), applicable to all compiled REs
35 * regardless of the size of their characters, whereas the stuff in
36 * regcomp.c gets compiled once per character size.
