No they aren't the same.  But there is no M$ compiler for ubuntu and I 
want to try something other than gcc.  Given that we expect the i7 to be 
about 20-40-60% faster than the i5, and I'm seeing up to 10x speed 
increase, one possible explanation is that the M$ compiler generates 
superior code than gcc (for povray anyway).

Reading this red vs. blue page
https://software.intel.com/en-us/forums/intel-c-compiler/topic/327585
it looks like maybe I can play with the optimizations on gcc. -- I 
haven't checked if povray _already uses_ the suggested optimizations, or 
if they're even viable, in which case I'm back to pining for icc.

I've generated 94,772 frames [1] on my 4 Ubuntu boxes in the last 4 
months.  Anything I could do to speed that up would be great. (other 
than changing my superellipse floor to boxes ;) )
