[Ffmpeg-devel] Mac OS X Intel part 3: binary integer constants

[John Dalgliesh]

Hi, here's part 3 (of 4) of the patches. It's trivial: Apple's as only 
understands the same integer constants as C does: hex, decimal, octal. It 
doesn't understand binary integer constants (0b...). Fortunately only one 
file in ffmpeg contains these: libavcodec/i386/idct_mmx_xvid.c

Attached patch replaces binary integer constants with hex ones.

Usual tests pass: .o files are identical, and no regressions are broken 
under linux (or under OS X ... if using a balign patch).
