Re: octave 2.9.9 under cygwin does not find scriptfiles on network path

For the record, 
The problem is solved in the 20061023 snapshot of the cygwin dll.

octave-2.9.9:1:~ > ls -l -a /cygdrive/u/foo
total 5
drwxr-xr-x 1 lindnebe DUsers 0 Nov  8 10:30 .
drwxr-xr-x 1 lindnebe DUsers 0 Jan  1  1970 ..
-rw-r--r-- 1 lindnebe DUsers 0 Nov  8 10:31 bar
-rw-r--r-- 1 lindnebe DUsers 0 Nov  8 10:31 baz
-rw-r--r-- 1 lindnebe DUsers 0 Nov  8 10:31 quuuux
-rw-r--r-- 1 lindnebe DUsers 0 Nov  8 10:31 quuux
-rw-r--r-- 1 lindnebe DUsers 0 Nov  8 10:31 quux
octave-2.9.9:2:~ > readdir('/cygdrive/u/foo')
ans =
{
  [1,1] = .
  [2,1] = ..
  [3,1] = bar
  [4,1] = baz
  [5,1] = quuuux
  [6,1] = quuux
  [7,1] = quux
}

Conclusio:
If you want to use octave 2.9.x on a w2k machine under cygwin, 
and you want to access files on a remote share,
then you must have a cygwin dll at least from 20061023 snapshot or later.
(I guess this fix will be included in the next release of the cygwin dll,
so you will need a cygwin dll version later than 1.5.21-1)
