Due to error in using autoconf, configure.ac replaces user-supplied CFLAGS with "default" ones.

Created attachment 320088 [details, diff] Simple patch for configure.ac illustrating the issue Doesn't apply with libav-ac.patch from tree. Problem is: one should never place any code prior to AC_INIT - it just don't make it into configure. In Gentoo, I suppose, we may just completely remove this "default flags" hack.
Reassign due to proxy maintainership.
your patch looks good to me, also I checked with upstream, they already accepted this fix with a very semilar patch. about the "default flags" hack, although I agree, fallback to a default CFLAGS is useless for gentoo distro, but doesn't hurt here, and also for upstream this will has minimal impact. thanks (In reply to comment #1)
Should be fixed in -r1 by upstream's patch (which just moves the offending line until after AC_INIT).
