After a little check gcc-4.7 does not support regular expressions yet...

a simple

       regex r("foo");
       char const *b="xfooz";
       char const *e=b+strlen(b);
       std::cout << regex_search(b,e,r) << std::endl;

Prints 0 (of course with boost::regex it prints expected result 1)

So it is too early to remove PCRE
