   Thanks for the answers. I knew there are been Vest and Aest, and that   
   VSI said there will not be any "Iest".   
      
   These specific RTL were used in the context of rendering picture by   
   Motif+x11. You needed them in the link phase.   
      
   I don't remember why Digital/Compaq/HP created these Vested and Aested   
   RTL. However the source code of them has never been accessible for   
   users. I hope Digital/Compaq/HP had the sources but/and I don't know the   
   specific issues which involved their choice of Vesting and Aesting them.   
      
   As a technical point, it is a very interesting subject.   
      
   But in the term of a port to x86, it could be a blocking point. I'm just   
   in the beginning of investigation on that. I'm not sure the applications   
   I have to analyze really use these libraries. I only remember that I   
   made a port to Itanium of similar applications ten or twenty years ago,   
   and it has been helpfull getting Aested libraries.   
      
   For both these interests, any information is wellcomed.   
      
   (And no, no link with Ada, Simon. I have a life beyond Ada :) ).   
      
   Thanks,
