-- 803abc2dcad8b2354c988e9bf58dac4a17683832 by Gennadiy Rozental <rogeeff@google.com>: Avoid warning when RTTI is not enabled. PiperOrigin-RevId: 294247546 -- 5a7b0b4d07d1d6e56fbb0b0ffbf4f8fcab772dbf by Derek Mauro <dmauro@google.com>: Add a public Abseil FAQ PiperOrigin-RevId: 294226960 -- 6945c4a6df7d7679711fea31aacf4fba6ac7baa1 by Gennadiy Rozental <rogeeff@google.com>: Re-enable type mismatch check, which works in all the cases including shared libraries. We will use RTTI in case when our hand written approximation of it reports a type mismatch. This way we can ensure that if a flag is defined in one shared object and referenced in another we do not report spurious errors.
