[FFmpeg-devel] [PATCH] Fix warnings in decode_significance_x86 and decode_significance_8x8_x86 (in h264_i386.h)

[Eli Friedman]

Patch attached; adds extra casts so gcc doesn't warn about truncating
pointers.  Someone else should double-check that this is the intent,
though; truncating pointers is an unusual operation, although it looks
like it's okay in this case.
