  Log:
  Fix a problem relating to fesetenv() clobbering i387 register stack.
  
  Details: As a side-effect of restoring a saved FP environment,
  fesetenv() overwrites the tag word, which indicates which i387
  registers are in use.  Normally this isn't a problem because
  the calling convention requires the register stack to be empty
  on function entry and exit.  However, fesetenv() is inlined, so we
  need to tell gcc explicitly that the i387 registers get clobbered.
