	* init.c: Do not try to mess with the MSR values in RTP mode:
	not needed and forbidden.

2015-11-12  Ed Schonberg  <schonberg@adacore.com>

	* exp_attr.adb (Compile_Stream_Body_In_Scope): Do not install
	full view of a type that has pragma Stream_Convert, because
	this indicates special processing for the stream operations of
	the type.
