Includes count of serious errors + -- and non-serious errors, so this value is always greater than or + -- equal to the Serious_Errors_Detected value. + + Warnings_Detected : Nat; + -- Number of warnings detected + + Current_Error_Source_File : Source_File_Index; + -- Id of current messages. Used to post file name when unit changes. This + -- is initialized to Main_Source_File at the start of a compilation, which + -- means that no file names will be output unless there are errors in units + -- other than the main unit.

This is used for defending against junk + -- resulting from illegalities, and also for substitution of more + -- appropriate error messages from higher semantic levels.
