I'm sorry, but I am going to respectfully disagree.  Full IEEE
comformance is very expensive on the Alpha's and the reason you need it
very uncommon.  Martin provoked it by passing a denormal to libg2c, but
*in normal programming* running into denormal should point to some error
in the logic of your algorithms.

[ Unless you're in cosmology and try to express everything in 32-bit
  REALs using SI units - my point is that nobody *does* that. ]
