-- HOST Parameters --
---------------------
Direct_Separator : constant Character;
pragma Import (C, Direct_Separator, "__gnat_dir_separator");
Normalized_CWD : constant String := "." & Direct_Separator;
-- Normalized string to access current directory
Max_Line_Length : constant :=
Types.Column_Number'Pred (Types.Column_Number'Last);
-- Maximum source line length. By default we set it to the maximum
-- value that can be supported, which is given by the range of the
-- Column_Number type. We subtract 1 because need to be able to
-- have a valid Column_Number equal to Max_Line_Length to represent
-- the location of a "line too long" error.
--
-- 200 is the minimum value required (RM 2.2(15)). The value set here
-- can be reduced by the explicit use of the -gnatyM style switch.
Max_Name_Length : constant := 1024;
-- Maximum length of unit name (including all dots, and " (spec)") and
-- of file names in the library, must be at least Max_Line_Length, but
-- can be larger.
Tag_Errors : constant Boolean := True;
-- If set to true, then brief form error messages will be prefaced by
-- the string "error:". Used as default for Opt.Unique_Error_Tag. Disabled
-- by gnatd_U.
Exclude_Missing_Objects : constant Boolean := True;
-- If set to true, gnatbind will exclude from consideration all
-- non-existent .o files.
