[Ada-mode-users] Grammar issue for gpr package Naming

[Simon Wright]

I have this project file:

--  Build the tools used for running the ACATS gnat-specific grading
--  scripts.
--
--  Assumes that the support code, stored as at
--  https://github.com/simonjwright/ACATS, is in ../ACATS.

project Tools is

   for Main use ("gnatscrp.a", "gnatevnt.a", "tstamp.a",
                 "summary.a", "grade.a");

   for Exec_Dir use ".";
   for Source_Dirs use (".", "../ACATS/support");
   for Object_Dir use ".build";

   package Naming is

      for Body ("gnatscrp") use "gnatscrp.a";
      for Body ("gnatevnt") use "gnatevnt.a";
      for Body ("tstamp") use "tstamp.a";

      for Body ("summary") use "summary.a";
      for Body ("grade") use "grade.a";

      for Spec ("trace") use "trace.a";

      for Spec ("grading_data") use "grd_data.a" at 1;
      for Body ("grading_data") use "grd_data.a" at 2;
      for Spec ("special_handling") use "special.a" at 1;
      for Body ("special_handling") use "special.a" at 2;
      for Spec ("test_summary") use "tst_sum.a" at 1;
      for Body ("test_summary") use "tst_sum.a" at 2;

   end Naming;

end Tools;

and 6.1.0 from elpa doesn't like the 'use "grd_data.a" at 1;' syntax (for info, 
it means that this is a file with more than one unit in it, which you'd 
normally gnatchop, but GNAT knows to use the first for this spec (I dare say it 
uses gnatchop internally?))

I don't understand how the parsing code gets generated, and I'm having real 
trouble with mtn, or I'd see if I could work something out.
