I reinstalled, reinstalled and reinstalled the before mentioned versions 
with trial and error process on cygwin and now it seems to work much better 
even if I see occasional errors but now they might be genious bugs.

Install first ATLAS. Use only ./configure in octave-forge-2004.11.16

INSTALL.WINDOWS in octave-forge-2004.11.16 seems to be a good source of 
trouble in cygwin. At least if you don't know what the instructions mean. 'A 
little bit of knowledge is a dangerous thing.' effect is in work here.

I think Octave Forge might be less dangerous if it were packaged with 
NOINSTALL defaults. I was looking for MATLAB-compatility there but I suspect 
that I have installed some broken pieces too in the process, which I haven't 
noticed yet. Hopefully I can continue in my ignorance.

fopen is slightly incompatible. MATLAB's fopen('file.name','wr'); causes 
internal error in Octave. I replaced it with fopen('file.name','w'); .

Octave Forge's ./configure assumes that the previous attempt of installation 
has not broken Octave completely which is a realistic scenario. Well, 
./configure works somehow even if Octave is slightly broken.
