Had the same error today when building beta1 on a Slackware current  
installation.
The header file (ioprio.h) included in Slackware is somehow incompatible  
with beta1.

To fix try to update your header files. I did this and got things to  
compile.
Not sure if it is recommended to update header files like that, so be  
careful ;)
