This is a bug fix release.
The new `reconnect` method introduced new struct members, which clashed with pre-defined names in pre-C99 code.
Another commit forced C99 compilation just to make it work, but of course this is not desirable for outside projects.
Other non-C99 code can now use hiredis as usual again.
Sorry for the inconvenience.
