1. I thought that a lot of the performance improvements seen under
   Digital Unix were due to a better libm implementation.  Does anyone
   have an idea of how much is attributable to DEC C vs egcs (say) &
   how much is attibutable to the *implementation* of libm?
2. Are there licensing problems with compiling & statically linking an
   application under Digital Unix & then running the application on a
   linux/alpha box?  I thought the only problem was moving the dynamic
   libraries around.  Am I also unable to move around applications
   statically linked against the Digital Unix libraries?
