This is duplicating code from compiler flag checking that was once
added (then reverted to CMake) as the problem seem to be on the
clang side as detailed in:
http://public.kitware.com/Bug/view.php?id=13194
I also tried to remove a similar warning with pthreads but there
is also an issue on the clang side:

the sizes are already validated by CheckSizeForOverflow(), add casts to
size_t to avoid -Wshorten-64-to-32
Change-Id: Ida9102c2104f4a334a0ad16d6e01a12bedfd4eec
(cherry picked from commit 1e2e25b0d4)
this corrects the checkboard pattern displayed with transparent images

(cherry picked from commit 67c25ad5b4)
In GenerateCandidates(), when candidate_ll->evaluate_ and
candidate_lossy->evaluate_ are both true, if lossless encoding
exits on error, candidate_ll->evaluate_ would not be correctly
reset. This will cause freeing uninitialized memory pointer in
SetFrame().
BUG=webp:322
Change-Id: I481b49a186e4fa3607ce71b4543a481083edf444
(cherry picked from commit 3ebe1c0003)
This improves compression by ~5% at default quality.
If only 'allow_mixed' is on (but 'minimize_size' isn't), we continue to
use a heuristic to try one of the two or both.

Passing the 'verbose' flag to DecodeWebP() wasn't mandated,
and was creating a forced dependency between imageio/ and examples/

fbba5bc optimize predictor #1 in plain-C For some reason, gcc has hard
time inlining this one...

WebPDecoder.framework replaces WebP.framework as the decode-only
framework.
WebP.framework now includes the full library allowing for use of the
encoder.

Set enc->prev_candidate_undecided_ as 0 when a frame is not chosen
as a possible keyframe, so that the dispose method can be
dispose-to-background.
