I've had to use two digit version numbers when upgrading frameworks during
the 5.4 development phrase. This meant that version_compare('5.4', PHP_VERSION);
would return -1 for things like 5.4.0-beta1. Padding the 5.4 to 5.4.0 would've
broken the comparison, as well as changing the return value of
version_compare('5.4', PHP_VERSION); when running 5.4.0.
