Subject: Plotting problem with grace

Hi,
I have just succeeded getting octave (2.9.2) and octave-forge
(2004-11-16) to compile on Cygwin with a gcc-3.3.3 compiled with
--disable-sjlj-exceptions. This increased loop execution speed by a
factor of at least 10.
I have also installed grace (5.1.18) and am trying to use it as
2D-plotting tool in octave.
However, just doing a simple plot produces a whole bunch of error
messages (but the plot appears anyway): (using toggle_grace_use to
switch to grace)

Octave:2> a=rand(100,1);
octave:3> plot(a)

Any idea?

Thanks
Reiner
