the tidy php extension tries to call tidyReleaseDate to get some
silly version string, but the library symbol doesnt exist for it
to resolve. this points it at tidyVersion instead.
you can reproduce the problem this solves by enabling the tidy
extension and running "php-5.3 -i" or by writing a script that calls
phpinfo(). they should segfault after complaining about a missing
the only caveat to this is the meaning of tidyReleaseDate doesnt
map well to what tidyVersion returns now (which is a version number),
but i dont care.
im happy for someone else to commit this at the most appropriate
