newlib math bug

I found a problem in the math libraries. Many functions contain the
following
fragment:

     if (exc.err != 0)
        errno = exc.err;

However, exc.err is never initialized so you can get very weird errno
values when an error occurs.

p.s. Is there a way to get read only access to the newlib CVS root so
       I can track bug fixes and updates ???
