I compiled 4.4.0 from the source tarball using gcc 4.2.4 on an OpenBSD 4.6-stable i386 laptop.
Plots using the x11 terminal show only the plot curves and the sample
lines for the key -- there are no borders, axes, tics, or text in the key! Attached is an X screen dump
(converted to a jpeg image) showing this. This behavior (bug) was NOT
present in gnuplot 4.2.6 (same gcc, same OS release, same platform, same ~/.gnuplot and ~/.Xdefaults),
and is NOT present for 4.4.0 plots using the postscript terminal).
Attachments: I am attaching 5 files:

without borders, axes, tics, or text in the key
