errout.adb (Write_Error_Summary): Do not output the number of lines when Main_Source_File is unknown. 

2013-10-14  Vincent Celier  <celier@adacore.com>

	* errout.adb (Write_Error_Summary): Do not output the number
	of lines when Main_Source_File is unknown.
	(Output_Messages): Do not write the header when Main_Source_File is
	unknown.

2013-10-14  Vincent Celier  <celier@adacore.com>

	* prep.adb (Expression): Accept terms of the form 'symbol <relop>
	integer", where relop is =, <, <=, > or >=.
	(Parse_Def_File): Accept literal integer values.
	* gcc-interface/Make-lang.in: Add s-valint.o, s-valuns.o and
	s-valuti.o to the compiler object files.
