Xfce4 session 4.5.91 doesn't compile

[Ali Abdallah]

Hi,

I'm trying to compile Xfce beta, in the configure script for 
xfce4-session i got the following warning:

WARNING: linux/ioprio.h:  present but cannot be compiled
WARNING: linux/ioprio.h:  check for missing prerequisite headers ?
WARNING: linux/ioprio.h:  see the Autoconf documentation
WARNING: linux/ioprio.h:  section "present but cannot be compiled"
WARNING: linux/ioprio.h: proceeding with the preprocessor's result
WARNING: linux/ioprio.h: in the future, the compiler will take precedence
WARNING: linux/ioprio.h:  report this to the xfce4-dev at xfce.org

and after trying to compile: derederencing pointer to incomplete type 
for line 50,51,58,59 in ioprio.h

the alpha version compiles on my system, kernel version 2.6.24.7.

it seems that i'll not be able to see the pluggable window settings today.
Best Regards,
Ali.
