back_end.adb: Remove Big_String_Ptr declarations (now in Types)
2008-04-08 Robert Dewar <dewar@adacore.com> * back_end.adb: Remove Big_String_Ptr declarations (now in Types) * errout.adb: Remove Big_String_Ptr declarations (now in Types) Change name Is_Style_Msg to Is_Style_Or_Info_Msg * fmap.adb: Remove Big_String declarations (now in Types) (No_Mapping_File): New Boolean global variable (Initialize): When mapping file cannot be read, set No_Mapping_File to False. (Update_Mapping_File): Do nothing if No_Mapping_File is True. If the tables were empty before adding entries, open the mapping file with Truncate = True, instead of delete/re-create. * fname-sf.adb: Remove Big_String declarations (now in Types) * s-strcom.adb, g-dyntab.ads, g-table.ads, s-carsi8.adb, s-stalib.ads, s-carun8.adb: Add zero size Storage_Size clauses for big pointer types * table.ads: Add for Table_Ptr'Storage_Size use 0 * types.ads: Add Big_String declarations Add Size_Clause of zero for big pointer types From-SVN: r134022
