1. get and unpack the scummvm src:
http://helllabs.org/scummvm/scummvm-20100201.tar.bz2
2. ./configure --enable-all-engines
3. edit config.mk so that CXXFLAGS :=  -O2 -funswitch-loops -ftree-loop-linear
-floop-interchange -floop-strip-mine -floop-block -ftree-loop-distribution
-ftree-loop-im -ftree-loop-ivcanon -fivopts -ftree-vectorize

-fgcse-after-reload -fgcse-sm -g  -ansi -W -Wno-unused-parameter
-Wno-empty-body -pedantic

4. edit config.mk so that LDFLAGS reads as "-lm -flto -fuse-linker-plugin
-fwhole-program"
5. make

result:
engines/cine/gfx.cpp: In member function ‘virtual void

Should this fix also be backported to 4.4? I'll test your fix this weekend.

------- Comment #8 from spop at gcc dot gnu dot org  2010-02-11 20:56 -------
I wouldn't recommend to backport this to 4.4, as Graphite in 4.4 has a
completely different structure.
