* 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.
