+
+ * sem_prag.adb (Check_No_Link_Name): New procedure.
+ (Process_Import_Or_Interface): Use Check_No_Link_Name.
+ * cstand.adb (Create_Standard): Use Esize (Standard_Long_Long_Float)
+ instead of Standard_Long_Long_Float_Size global. Preparation for
+ eventual removal of per type constants.
+ * exp_util.ads (Get_Stream_Size): New function returning the stream
+ size value of subtype E.
+ * exp_util.adb (Get_Stream_Size): Implement new function.
+ * exp_strm.adb (Build_Elementary_Input_Call): Use Get_Stream_Size
+ function.
+ * exp_attr.adb (Attribute_Stream_Size): Use Get_Stream_Size
+ * einfo.adb:
+ (Machine_Mantissa_Value): Handle 128-bit quad precision IEEE floats

* cstand.adb: Fix comments.
