I am trying to run numarray on Cygwin.
(Where Numeric seems to work fine.)

In order to compile it I had to change the use of round to rint, as
Cygwin's C library (newlib) doesn't have round.  The patch is
attached.

When I use it I don't get far, though:

If I print out the type of cfunc down in _doit, I get (the expected)

`----

Any ideas, probably some hints how to proceed?

Greetings,
Jochen
