* qatar/master: (31 commits)
  ARM: add ARMv6 optimised av_clip_uintp2
  ARM: remove volatile from asm statements in libavutil/intmath
  ARM: fix av_clipl_int32_arm()
  v4l: include avdevice.h
  ffserver: move close_connection() call to avoid a temporary string and copy.
  lavf: initialize demuxer private options.
  AVOptions: set string default values.
  lavdevice: mark v4l for removal on next major bump.
  swscale: fix compile on ppc.
  swscale: fix compile on x86-32.
  build: Remove generated .version file on distclean.
  configure: Add -D_GNU_SOURCE to CPPFLAGS on OS/2.
  doc: Drop hint at --enable-memalign-hack for MinGW, it is now autodetected.
  ffplay: Remove disabled code.
  Mark parameterless function declarations as 'void'.
  swscale: use av_clip_uint8() in yuv2yuv1_c().
  swscale: remove VOF/VOFW.
  swscale: split chroma buffers into separate U/V planes.
  swscale: replace formatConvBuffer[VOF] by allocated array.
  rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions.

FFmpeg automatically passes @code{-fno-common} to the compiler to work around
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
Within the MSYS shell, configure and make with:
@example
./configure --enable-memalign-hack
make
make install
@end example
This will install @file{ffmpeg.exe} along with many other development files
to @file{/usr/local}. You may specify another install path using the
@code{--prefix} option in @file{configure}.
