You do *not* want to implement a regular expression engine.  Use
regex(3) (which is POSIX), regexp(3), PCRE, or some similar
implementation, instead; I realize that you have a link to
pathological PCRE behavior, and I can't guarantee that the POSIX regex
implementation is better on any given platform, but in the real world
it won't matter.  The bugs in a custom-rolled regex implementation are
sure to be more annoying.  ;-)
