(mostly-)POSIX regular expressions

[Sébastien Boisgérault]

Very good hint ! I wouldn't have found it alone ...

I have to study the doc, but the "THE DFA MATCHING ALGORITHM" may do
what I need Obviously, I didn't expect the Perl-Compatible Regular
Expressions to implement
"an alternative algorithm, provided by the pcre_dfa_exec() function,
that operates in a different way, and is not  Perl-compatible".

Maybe the lib should be renamed in PCREWSO for:
Perl-compatible regular expressions ... well, sort of :)

Cheers,
