Ok, with the help of someone from IRC i found out that there is a long living
problem with gcc and it's use of -O3. Many people who compile anything with
-O3 most likely come across problems later on and dont know why. Compiling
everything with -O2 or less fixes the problem. I recompiled X, qt, and
then avifile. Everything but qtrecompress compiled and is running
successfully. Save that known xlib resize problem that's being fixed.
On a sidenote to anyone else using gcc 3.x. So, far it appears that qt 2.3.1
compiled by GCC 3.x can co-exist with qt 2.3.1 compiled by your distro (2.95)
as i've not yet had problems with kde apps using the new library even though
it comes before in the ld path. They are still using the old qt lib. Just
make sure you dont compile anything with -O3. It is evil.
