Your patch conflicts with my efforts to maintain compatibility with Octave.
Especially it breaks compatibilty of http://BIOSIG.SF.NET in some 
application cases. Because, I assume that these are rare applications or 
use Matlab anyway, it should be ok if you go ahead with this.

I'll do the required changes in my code, but I also ask you to make sure 
that
a new version of Octave4Windows is available soon. It should accept the 
't' flag, currently it does not.
