Dear Prof. Hodel, 

Your student's error message about no entry point for
some procedure in cygwin1.dll is likely due to your
student having a very old version of cygwin. (I
experienced a similar error using a year 2000 version
of cygwin.) 

He or she might try installing the current version of
cygwin. Do that at http://cygwin.com/. 

Alternatively, one could try using one of the
precompiled Windows / Cygwin Octave-forge binaries such
as 

    http://sourceforge.net/project/shownotes.php?release_id=174240

These self-installing packages not only include the
Octave files but also the minimal set of Cygwin files
needed for it to run. (However even if you choose this
route, it is still advisable, probably necessary, to
uninstall any old version of cygwin.) 

About gnuplot, its up to you to manually move the
executables to the correct directory. For octave
running under cygwin, the correct directory will be
something like c:\cygwin\usr\local\bin. Cygwin and
Octave require a Unix-like directory structure (e.g.,
/usr/local/bin). If you mess with that structure, 
neither Octave nor Cygwin will work well or at all.
