procedure Add_Dependency (S : Source_File_Index);
-- Add a dependency on a non-source file. This is used internally for the
-- preprocessing data file and the preprocessing definition file, and also
-- externally for non-temporary configuration pragmas files.
procedure Add_Dependencies;
-- Add dependencies on the preprocessing data file and the preprocessing
-- definition files, if any, and the non-temporary configuration pragmas
-- files, if any.
procedure Check_Symbols;
-- Check if there are preprocessing symbols on the command line and set
-- preprocessing if there are some: all files are preprocessed with these
-- symbols. This procedure should not be called if there is a preprocessing
-- data file specified on the command line. Instead a call should be made
-- to Parse_Preprocessing_Data_File.
procedure Parse_Preprocessing_Data_File (N : File_Name_Type);
-- Parse a preprocessing data file, specified with a -gnatep= switch
procedure Prepare_To_Preprocess
(Source : File_Name_Type;
Preprocessing_Needed : out Boolean);
-- Prepare, if necessary, the preprocessor for a source file. If the source
-- file needs to be preprocessed, Preprocessing_Needed is set to True.
-- Otherwise, Preprocessing_Needed is set to False and no preprocessing
-- needs to be done.
procedure Process_Command_Line_Symbol_Definitions;
-- Check symbol definitions that have been added by calls to procedure
-- Add_Symbol_Definition and stored as pointers to string, and put them in
-- a table. The reason the definitions were stored as pointer to strings is
-- that the name table is not yest initialized when we process the command
-- line switches. These symbol definitions will be later used in
-- the call to Prepare_To_Preprocess.
