system-lynxos-ppc.ads, [...]: Increase default priority on Lynx from 15 to 17... 

2005-11-14  Matthew Gingell  <gingell@adacore.com>

	* system-lynxos-ppc.ads, system-lynxos-x86.ads: 
	Increase default priority on Lynx from 15 to 17, and meet the Ada
	requirement that Default_Priority be ((Priority'First +
	Priority'Last) / 2) by increasing the range of Interrupt_Priority.
