On my system, gnuplot 4.2 and 4.3 (CVS) both accept "set
term".
To double-check, I just downloaded and built the latest official
release, version 4.2.3: "set term" works fine.

Yes, here in that same version it is also working fine.
To validate the BUG, I installed the official gretl 1.7.4, but
now sometimes, I cannot even produce a chart. The program
crashes. And now it crashes for other reasons too (missing
symbol from liblapack.so.3).
If I understood your earlier reply to Jack correctly, you said
you'd switched the linking order for gretl from "-llapack -lblas"
to "-lblas -llapack". If that's so, it could cause problems with
unresolved symbols. The point is that gretl uses no symbols from
libblas; it uses symbols from liblapack, which in turn requires
symbols from libblas. The order in which the libraries are given
to the linker must reflect this. If you give "-lblas" first, the
linker thinks "libblas? We don't need anything from that, just
move along".
But never mind this for now, I have been always using the CVS
version, and fixed the original BUG (I believe did check that it
existed in the Windows version).
Please reproduce the BUG:
Create a chart, for example a time-series.
Right click over it, and Save as a PNG...
This works for me, but I will check on Windows and with the
official gnuplot 4.2.3 release.
