When gnuplot-3.7 came out, this problem was mentioned to one of the
gnuplot discussion groups (which I don't normally read, I use gnuplot
only occasionally, with octave, for example). It didn't get much
attention, because it seems to affect only linuxppc (and who's using
that, anyway?)

Yes, I compiled gnuplot-3.7 under glibc-961212 (rev 1o, IIRC), and the
result was the same. I managed to track the problem down to the fprintf
call, but I don't know enough C and glibc to go any further.
