Re: more on proff crash building native

[Brad Parker <brad%heeltoe.com@localhost>]

fyi: I looked at the diffs between the trunk and netbsd-3 for
src/lib/libm/arch/vax/n_sqrt.S and applied just the branch fix (below).

I then rebuild it all (in cross compile) and installed.  Now my
test program passes. I think this fixes the groff crash.  I'll try
a native build next.

Can we get this applied to netbsd-3 & netbsd-4 or is that considered a
waste of time?
