Working PERL script

I am trying to get the following regexp to work:

(?(?=.*b)b|^)

This matches (in pcre) "adc" but not "abc". If I replace the ^ with something
else like a-z or $ then the regexp matches.

I have tried the pattern in perl v5.8.8 and it works.

I have attached a simple perl script that work the way I expect and some C
using PCRE that does not.

Cheers,
Mick
