This works fine for building octave (although I've noticed
with cygwin on pentium 4's, configure doesn't get the
host correctly, so you have to do
./configure --build=i686-pc-cygwin --host=i686-pc-cygwin )

However, there is a trick for gnuplot.

1. Get win32 gnuplot from www.gnuplot.org. Install it
at Drive:/path/to/wgnuplot.exe

2. Get pipe-gnuplot.exe, put it in you PATH

3. In octave, set
gnuplot_binary="pipe-gnuplot.exe Drive:/path/to/wgnuplot.exe"

4. from cygwin,
mount Drive:/tmp /tmp

This last step is important, so that octave and gnuplot can
co-operate about where the temprorary files are stored, since
octave uses cygwin directory naming, and gnuplot uses
win32 naming.

Additionally, if you want image() to work, you need to 
edit image.m to add the image viewer of your choice

For example, change the line
  xv = sprintf ("xv -expand %f %s", zoom, ppm_name);
to
  xv = sprintf ("i_view32 %s", ppm_name);
I use i_view32 from irfanview.com, as I don't know of
another win32 viewer that understands ppm images.


Hope this helps
