Well, mabye.  I'm far from certain that apparently not seeing the last
few chars on a line is not the same bug...

below is the result of the following awkscript, run on input files
gawk-2.15.5/test/manpage, and diff'ing Ultrix and NetBSD-pmax output.
It seems to me like the last word on each line is consistently
being lost.  It turns out that if I change the loop test from
``i <= NF'' to ``i <= NF + 1;'' the NetBSD awk gives the
``right'' answer. So it looks like NF is being set incorrectly.

Where might I look to see that? Is it plausible that gawk is keeping
its NF in floating-point internall, and a badly-broken floating point
ascii <-> decimal is causing this bug?  That was my first guess...

I just hope this isn't a bug in the gcc-2.5.8 mips backend!

--------begin example awkscript
# From Gawk Manual modified by bug fix and removal of punctuation
# Record every word which is used at least once
{
        for (i = 1; i <= NF; i++) {
                tmp = tolower($i)
                if (0 != (pos = match(tmp, /([a-z]|-)+/)))
                        #used[substr(tmp, pos, RLENGTH)] = 1
                        print tmp
        }
}
