This comparison info is very handy.  It is at least good to see (well, in
this trival case) that NetBSD-1.4.3 and NetBSD-1.5 w/gcc 2.91 seem to be
about on par with eachother.

IIRC, the earlier non-stripped kernel compile benchmarks you posted showed
a much greater performance discrepancy between NetBSD 1.4.3 and 1.5.
Maybe that's still the case when compiling something intensive like the
kernel where the compile processes will go into swap more often.
