[ooo-build] gcc4.4: extensions broken when compiled with default -O2 optimizations

[Andreas Radke]

installing extensions is broken since we use gcc4.4 with -O2
optimizations. see http://bbs.archlinux.org/viewtopic.php?id=71043

I found this in my build.log:

Where can I set -fno-strict-aliasing for this certain module to test if this solves it?

Which makefile.mk sets the flags?
