[multiple changes]

2017-01-06  Bob Duff  <duff@adacore.com>

	* bindgen.adb (Gen_Adainit, Gen_Adafinal): Change
	"Bind_Main_Program" to "not Bind_For_Library", because otherwise
	we won't generate the call to s_stalib_adafinal when the main
	is not written in Ada.

2017-01-06  Bob Duff  <duff@adacore.com>

	* sem_prag.adb: Minor: remove pragma Warnings.

2017-01-06  Tristan Gingold  <gingold@adacore.com>

	* Makefile.rtl: Do not compile s-stchop by default.
