* commit 'c0329748b04e1f175dad8c9c2ebf22a5e2dc5b72':
  fate: add a dependency helper macro
  Add support for building shared libraries with MSVC
  avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tab
  gxf: Add a local copy of the relevant parts of the frame rate table
  configure: Split out msvc as a separate target OS
  aviobuf: Remove a senseless ifdef in avio_seek

Conflicts:
	configure
	libavcodec/dirac.c
	libavcodec/mpeg12data.h
	libavcodec/mpeg12enc.c
