I think I understand.  However, I may have added this flag when I built libc
[I do to everything else].  Also:

1) I thought alignment was a big performace win on 686's?

2) What about the other -malign- ix86 options?  For example, the default ix86 
makefile used to build the linux kernel has loads of these.
