Subject: Re: problems using SEQUENTIAL_IO

Your problem with Sequential_IO is GNAT specific and should be addressed
to gnat-report AT cs DOT nyu DOT edu.  However to save you time the answer is:

(from the README file)
Sequential_IO Note: Feb 16, 1995 :15:50 EST

   In GNAT 2.03 all instantiations of sequential_io will get the message:
   a-sequio.adb:33:59: actual for "Element_Type" must be a definite subtype

   The workaround is simple. Modify the type declaration of Element_Type on
   line 22 of adainclude/a-sequio.ads and remove the (<>). This should solve
   the problem.

   Note : This is a glitch in our current implementation of Sequential_IO,
   which will be fixed ASAP. In the meantime, the proposed workaround
   restricts one to instantiate Sequential_IO only with constrained types.
