system-vxworks-sparcv9.ads, [...]: Document mapping between Ada and OS priorities.

2007-04-20  Arnaud Charlet  <charlet@adacore.com>

	* system-vxworks-sparcv9.ads, system-solaris-x86.ads,
	system-irix-o32.ads, system-freebsd-x86.ads, system-lynxos-ppc.ads,
	system-lynxos-x86.ads, system-vxworks-m68k.ads, system-linux-x86.ads,
	system-vxworks-mips.ads, system-vxworks-alpha.ads,
	system-vxworks-x86.ads, system-linux-ppc.ads, system-mingw.ads,
	system-vms-zcx.ads, system-darwin-ppc.ads, system-vxworks-ppc.ads,
	system-interix.ads, system-linux-hppa.ads, system-tru64.ads,
	system-hpux.ads, system-irix-n32.ads, system-solaris-sparc.ads,
	system-solaris-sparcv9.ads, system-vms.ads, system.ads,
	system-vms_64.ads, system-hpux-ia64.ads, system-linux-x86_64.ads,
	system-linux-ia64.ads: Document mapping between Ada and OS priorities.
	This patch changes the largest non-binary modulus from 2**31-1 to
	2**32-1.
	(Compiler_System_Version): Removed, no longer used.
	Clean up system files by removing flags only used on a single target.
	Also remove obsolete flags, only used during bootstrap from system.ads
	(Address): Add a pragma Preelaborable_Initialization.

	* system-aix.ads:  Ditto.
	(GCC_ZCX_Support): Set to true.
	Update priority range on AIX and map Ada priorities to target
	priorities appropriately for different scheduling policies.

	* ttypes.ads: set largest non-binary modulus from 2**31-1 to 2**32-1
