On having a grep in the source, I found this in targparm.ads:

   --  The corresponding string constant is placed immediately at the
start
   --  of the private part of system.ads if is present, e.g. in the
form:

   --    Run_Time_Name : constant String := "Zero Footprint Run Time";

   --  the corresponding messages will look something like

   --    xxx not supported (Zero Footprint Run Time)


   Run_Time_Name_On_Target : Name_Id := No_Name;
   --  Set to appropriate names table entry Id value if a
Run_Time_Name
   --  string constant is defined in system.ads. This name is used
only
   --  for the configurable run-time case, and is used to parametrize
   --  messages that complain about non-supported run-time features.
   --  The name should contain only letters A-Z, digits 1-9, spaces,
   --  and underscores.

Dunno, if this'll work if I just take the standard system.ads from gcc/
ada and modify it.

There is also an entry in system.ads:

   Configurable_Run_Time     : constant Boolean := False;

which seems to refer to the Run_Time_Name_On_Target above.
