Packaging changes

As of 2014-03-22, Cygwin packages have been moved into a custom repository directory. See http://www.libjpeg-turbo.org/Documentation/Cygwin for more details.

1.1.1

Significant changes relative to 1.1.0:

1. Fixed a 1-pixel error in row 0, column 21 of the luminance plane generated by tjEncodeYUV().

2. libjpeg-turbo's accelerated Huffman decoder previously ignored unexpected markers found in the middle of the JPEG data stream during decompression. It will now hand off decoding of a particular block to the unaccelerated Huffman decoder if an unexpected marker is found, so that the unaccelerated Huffman decoder can generate an appropriate warning.

3. Older versions of MinGW64 prefixed symbol names with underscores by default, which differed from the behavior of 64-bit Visual C++. MinGW64 1.0 has adopted the behavior of 64-bit Visual C++ as the default, so to accommodate this, the libjpeg-turbo SIMD function names are no longer prefixed with an underscore when building with MinGW64. This means that, when building libjpeg-turbo with older versions of MinGW64, you will now have to add -fno-leading-underscore to the CFLAGS.

4. Fixed a regression bug in the NSIS script that caused the Windows installer build to fail when using the Visual Studio IDE.

5. Fixed a bug in jpeg_read_coefficients() whereby it would not initialize cinfo->image_width and cinfo->image_height if libjpeg v7 or v8 emulation was enabled. This specifically caused the jpegoptim program to fail if it was linked against a version of libjpeg-turbo that was built with libjpeg v7 or v8 emulation.

6. Eliminated excessive I/O overhead that occurred when reading BMP files in cjpeg.

7. Eliminated errors in the output of cjpeg on Windows that occurred when the application was invoked using I/O redirection (cjpeg <inputfile >output.jpg.)
