2007-08-14  Jose Ruiz  <ruiz@adacore.com>

	* adaint.c (__gnat_is_absolute_path): For VxWorks systems we accept
	dir/file, device:/dir/file, and device:drive_letter:/dir/file as
	representing absolute path names.
	__gnat_set_file_time_name [VMS]: Fix some 64/32 bit issues.

	* cstreams.c (__gnat_full_name for VxWorks): Use
	__gnat_is_absolute_path to detect whether we need to add the current
	directory to normalize the path.
