Comment 35 for bug 383240

dsputil.h is not part of the public API, so changes there should not affect anything outside libavcodec.

There is no point in explicitly enabling ARM features (e.g. --enable-armv6) as these are automatically selected depending on the --cpu option. A NEON build should have everything enabled, since anything with NEON is also ARMv6[T2] compatible.

As for which changes to include, backporting the more extensive changes probably doesn't make much sense, at least not those depending on other changes to e.g. aac.c. Hopefully we'll make a new release (0.6?) at some point, which will include all these changes.
