Hmm.. It was reported as the potential reason for the bigger OpenBSD
kernel.

Now, that report may obviously have been bogus, of course. There may be
something else going on. Linux uses "-mpreferred-stack-boundary=2" exactly
because the default behaviour of newer gcc's is very much suboptimal
(certainly for the kernel, and I will bet that it is for most applications
compiled with gcc).
