Further examination of the code reveals that this change is unnecessary. The histogram stores a count of each color in the image, so it will always contain at least one non-zero element, and thus the total can never be zero. Since the histogram is generated from the image data and not read from the header, there is no chance that header corruption would affect it.

Some motion JPEG implementations generate "abbreviated JPEG streams" (JPEG images without the default tables included) for some or all of the video frames, in order to save space. When these are encountered, it is generally expected that they will be decompressed using the default Huffman tables, so libjpeg-turbo now does this unless the tables have been explicitly specified by an application.

Back-port code from jpeg-8 that removes unpopulated (and unneeded) tables for AC and DC coefficients when generating progressive JPEG files with arithmetic coding.

Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes.

Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1.

Due to the way in which the configure script silently falls back to a non-SIMD build if SIMD can't be enabled, we accidentally released iOS ARM v7 and v7s binaries in 1.3.0 that did not contain NEON SIMD code, because gas-preprocessor.pl wasn't in the PATH. In order to prevent this from happening again, specifying --with-simd now has the effect of forcing a SIMD build, and if this argument is specified, any issues encountered while enabling SIMD are treated as fatal.

In the Windows installer packages, place a duplicate copy of turbojpeg.dll in c:\libjpeg-turbo[-gcc][64]\bin. This is mainly to give installers an easy way to find the DLL for the purposes of bundling it. Specifically, this was necessary for TurboVNC, becuase 32-bit CMake running on 64-bit Windows cannot ever access the "real" c:\windows\system32 directory.
