All the compilers that are supported by ffmpeg (including MSVC) 
_already_ support DCE.  They must in order to be able to do any 
successful optimized builds.  So, I think this is really only relevant 
when optimizations are deliberately disabled, and I think it is 
reasonable to expect that DCE will be disabled if optimizations are 
disabled.
