I forgot to mention that the search for the files is included in the 
timings, which took 10-15s, so there _is_ actually a difference for 
complex regexps.
Despite of that, pcre also supports more character sets like [[:alnum:]] 
and other useful sequences, which, IMHO, is another reason to use pcre.

OK, that's a point against pcre. I'm thinking about to have the user decide which engine he wants to use.
