Hello!

I don't know if I did this the right way...
Here's the output, I started xfce4 using startxfce4 but commented out 
the panel and started an xterm instead.

Hmmm, "gdkdraw.c"... is that the problem?
And "no debugging symbols found" is bad?
My CFLAGS are "-march=athlon-xp -Os -mfpmath=sse -mmmx -msse -m3dnow 
-pipe" and my whole system is build that way and runs without any problems.

Hope that helps,
Marc.
