* s-parame-mingw.adb, s-parame-linux.adb,

	s-parame-solaris.adb: Removed, replaced by s-parame.adb

	* s-parame-vxworks.ads: Fix typo.

	* s-parame-vxworks.adb: New file.

	* s-parame.adb: Version now used by all native platforms.
	(Default_Stack_Size): Use 2 megs for default stack size and use
	__gl_default_stack_size when available.
	(Minimum_Stack_Size): Use 12K.

	* s-taprop-mingw.adb: Set default stack size linker switch to 2megs.
	(Create_Task): Refine implementation taking advantage of the XP stack
	size support. On XP, we now create the thread using the flag
	STACK_SIZE_PARAM_IS_A_RESERVATION.

	* s-osinte-mingw.ads (Stack_Size_Param_Is_A_Reservation): New constant.

	* sysdep.c (__gnat_is_windows_xp): New routine, returns 1 on Windows
	XP and 0 on older Windows versions.

	* interfac-vms.ads: Removed, no longer used.
