Subject: [ada] improve handling of env variables under VMS

Manually tested on VMS,
Tested on i686-linux, committed on HEAD

VMS uses environment variables (aka logical names) in a much more
sophisticated manner than Unix. They are oftimes used to define files so
it makes sense to check if a simple alphanumeric_ "filespec" is a logical
name and if so translate it before putting into canonical form.

	* adaint.c (__gnat_to_canonical_file_spec [VMS]): Check for logical
	name and translate.
