The conversion between OS and Ada priorties should be done in the wider
Interfaces.C.int type rather than Any_Priority otherwise
Constraint_Error will be raised when coverting Any_Priority'Last to int.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* libgnarl/s-osinte__qnx.adb (To_Target_Priority): Perform
arithmetic in int.
