2015-10-20  Thomas Quinot  <quinot@adacore.com>

	* Makefile.rtl: add the following...
	* g-binenv.ads, g-binenv.adb: New unit providing runtime access
	to bind time captured values ("bind environment")
	* init.c: declare new global variable __gl_bind_env_addr.
	* bindgen.ads, bindgen.adb (Set_Bind_Env): record a bind
	environment key=value pair.
	(Gen_Bind_Env_String): helper to produce the bind environment data
	called  in the binder generated file.
	(Gen_Output_File_Ada): Call the above (Gen_Adainit): Set
	__gl_bind_env_addr accordingly.
	* switch-b.adb: Support for command line switch -V (user interface
	to set a build environment key=value pair)
	* bindusg.adb: Document the above

2015-10-20  Vincent Celier  <celier@adacore.com>

	* sem_prag.adb (Analyse_Pragma: Pragma Pure): Do not set the
	entity as Pure if Debug_Flag_U is set.
