I'm not sure about what you're trying to do, but it seems you compiled
an oct-file using Octave/Cygwin and you try to use it under Octave/MSVC.
This is not gonna work, because both versions were compiled using
different C++ compilers, which are not compatible.

You can find useful information about Octave for Windows (the cygwin and
the MSVC versions) at http://www.geocities.jp/tmoctwin/ and about how to
use mkoctfile under Octave/MSVC at http://www.geocities.jp/tmoctwin/msvcoct.html
