Warn_On_Record_Holes : Boolean := False; -- Warn when explicit record component clauses leave uncovered holes (gaps) -- in a record layout. Off by default, set by -gnatw.h (but not -gnatwa). Warn_On_Overridden_Size : Boolean := False; -- Warn when explicit record component clause or array component_size -- clause specifies a size that overrides a size for the typen which was -- set with an explicit size clause. Off by default, set by -gnatw.s (but -- not -gnatwa). ----------------- -- Subprograms -- ----------------- function Set_Warning_Switch (C : Character) return Boolean; -- This function sets the warning switch or switches corresponding to the -- given character. It is used to process a -gnatw switch on the command -- line, or a character in a string literal in pragma Warnings. Returns -- True for valid warning character C, False for invalid character. function Set_Dot_Warning_Switch (C : Character) return Boolean; -- This function sets the warning switch or switches corresponding to the -- given character preceded by a dot. Used to process a -gnatw. switch on -- the command line or .C in a string literal in pragma Warnings. Returns -- True for valid warning character C, False for invalid character. procedure Set_GNAT_Mode_Warnings; -- This is called in -gnatg mode to set the warnings for gnat mode. It is -- also used to set the proper warning statuses for -gnatw.g. Note that -- this set of warnings is disjoint from -gnatwa, it enables warnings that -- are not included in -gnatwa, and it disables warnings that are included -- in -gnatwa (such as Warn_On_Implementation_Units, which we clearly want -- to be False for units built with -gnatg). end Warnsw;
