	* s-intman-vxworks.ads, s-intman-vxworks.adb (Abort_Task_Signal):
	Rename to Abort_Task_Interrupt to be able to keep the same interface
	as the rest of the targets.

	* s-osinte-vxworks.ads s-osinte-vxworks.adb
	(To_VxWorks_Priority): Remove explicit "in" mode indicator

	* s-osinte-vxworks6.ads, s-vxwork-arm.ads, system-vxworks-arm.ads:
	New files.
