x264 | branch: master | Jason Garrett-Glaser <darkshikari at gmail.com> | Thu Nov 12 05:25:32 2009 -0800| [cbd43d1e31fae533de121c7c0dfcc13ebf41aa24] | committer: Jason Garrett-Glaser 

Fix all aliasing violations
New type-punning macros perform write/read-combining without aliasing violations per the second-to-last part of 6.5.7 in the C99 specification.
GCC 4.4, however, doesn't seem to have read this part of the spec and still warns about the violations.
Regardless, it seems to fix all known aliasing miscompilations, so perhaps the GCC warning generator is just broken.
As such, add -Wno-strict-aliasing to CFLAGS.
