Comment (by tash):

 I'm reversing myself. I attempted to integrate your chebwin function into
 scipy/signal/signaltools.py . When I take the function, place it in there,
 and add 'numpy.' in front of the complained-about functions to get it to
 compile properly, I get the NaN problem again. I can confirm that the db
 parameter is positive. Could you take a swing at it and see if you can
 have any better luck? During my debugging, it seems to fall apart during
 the creation of 'p[]'.

 As an aside, I've also attached my implementation (from back when I was
 naive and couldn't get the original to work). I suspect that I lucked out
 of integration problems by using the special.chebyt function.
