+   -- TARGET Parameters --
+   -----------------------
+
+   --  ??? The following should really be moved to a Target package
+
+   Java_VM : constant Boolean := False;
+   --  Set true when compiling the JGNAT tool chain (compiler, gnatmake, etc)
+
+   ---------------------
+   -- HOST Parameters --
+   ---------------------
+
+   OpenVMS : Boolean := False;
+   --  Set True for OpenVMS host. See also OpenVMS target boolean in
+   --  5vsystem.ads and OpenVMS_On_Target boolean in Targparm. This is
+   --  not a constant, because it can be modified by -gnatdm.
+
+   Normalized_CWD : constant String := "./";
+   --  Normalized string to access current directory
+
+   Max_Line_Length : constant := 255;
+   --  Maximum source line length. This can be set to any value up to
+   --  2**15 - 1, a limit imposed by the assumption that column numbers
+   --  can be stored in 16 bits (see Types.Column_Number). A value of
+   --  200 is the minimum value required (RM 2.2(15)), but we use 255
+   --  for most GNAT targets since this is DEC Ada compatible.
+
+   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.
+
+   Max_Instantiations : constant := 4000;
+   --  Maximum number of instantiations permitted (to stop runaway cases
+   --  of nested instantiations). These situations probably only occur in
+   --  specially concocted test cases.
+
+   Tag_Errors : constant Boolean := False;
+   --  If set to true, then brief form error messages will be prefaced by
+   --  the string "error:". Used as default for Opt.Unique_Error_Tag.
+
+   Exclude_Missing_Objects : constant Boolean := True;
+   --  If set to true, gnatbind will exclude from consideration all
+   --  non-existent .o files.
+
+   Max_Debug_Name_Length : constant := 256;
+   --  If a generated qualified debug name exceeds this length, then it
+   --  is automatically compressed, regardless of the setting of the
+   --  Compress_Debug_Names switch controlled by -gnatC.
