45 -- preprocessing if there are some: all files are preprocessed with these
46 -- symbols. This procedure should not be called if there is a preprocessing
47 -- data file specified on the command line. Instead a call should be made

62 -- Check symbol definitions that have been added by calls to procedure
63 -- Add_Symbol_Definition and stored as pointers to string, and put them in
64 -- a table. The reason the definitions were stored as pointer to strings is
65 -- that the name table is not yest initialized when we process the command
66 -- line switches. These symbol definitions will be later used in
67 -- the call to Prepare_To_Preprocess.
