2009-04-17 Gary Dismukes <dismukes@adacore.com>
* par-ch6.adb (P_Subprogram): Overriding indicators should be allowed
on protected subprogram bodies, so exclude the case where Pf_Flags is
Pf_Decl_Pbod from the error check.
* par-ch9.adb (P_Protected_Operation_Items): Permit overriding
indicators on subprograms in protected bodies, and proceed with parsing
the subprogram.
* sem_ch6.adb (Verify_Overriding_Indicator): Exclude protected
subprograms from the check for primitiveness on subprograms with
overriding indicators.
(Check_Overriding_Indicator): Include protected subprograms in the
style check for missing overriding indicators.
2009-04-17 Tristan Gingold <gingold@adacore.com>
* init.c: Fix stack checking for x86 Darwin.
2009-04-17 Vincent Celier <celier@adacore.com>
* prj-attr.adb: New project level attribute Object_File_Suffix
(<language>).
* prj-nmsc.adb (Add_Source): Use the object file suffix to get the
object file name
(Process_Compiler): Process attribute Object_File_Suffix
* prj.adb (Object_Name): Use suffix Object_File_Suffix instead of
platform suffix, when specified.
* prj.ads (Language_Config): New component Object_File_Suffix,
defaulted to No_Name.
(Object_Name): New parameter Object_File_Suffix, defaulted to No_Name
* snames.ads-tmpl: New standard name Object_File_Suffix
