/* The value of LINK_SIZE determines the number of bytes used to store links
   as offsets within the compiled regex. The default is 2, which allows for
   compiled patterns up to 64K long. This covers the vast majority of cases.
   However, PCRE can also be compiled to use 3 or 4 bytes instead. This allows
   for longer patterns in extreme cases. On systems that support it,
   "configure" can be used to override this default. */

/* The value of MATCH_LIMIT determines the default number of times the

   pcre_exec(). There is a runtime interface for setting a different limit.
   The limit exists in order to catch runaway regular expressions that take
   for ever to determine that they do not match. The default is set very large
   so that it does not accidentally catch legitimate cases. On systems that
   support it, "configure" can be used to override this default default. */

   the depth of recursive calls of match() more strictly, in order to restrict
   the maximum amount of stack (or heap, if NO_RECURSE is defined) that is
   used. The value of MATCH_LIMIT_RECURSION applies only to recursive calls of
   match(). To have any useful effect, it must be less than the value of
   MATCH_LIMIT. The default is to use the same value as MATCH_LIMIT. There is
