Comment:

 The ticket now consists of five patches:

 #. trac4000_0.patch
 #. trac4000_1.patch
 #. trac4000_doctest_output.patch
 #. trac4000_fmpq_poly_c.patch
 #. trac4000_fmpq_poly_pxd.patch

 Only 0 and 1 have to be applied in this order.  The remaining patches can
 be applied in any order.  After having removed the methods for comparisons
 (which caused a problem as Harald noticed above), these should now
 hopefully be very, very close to finalised.  I've also included the signal
 handling around most C library calls.

 Best wishes, and many thanks for looking at this ticket!

 Sebastian

 PS:  Perhaps someone with the appropriate rights could delete all the
 unnecessary attachments to this ticket?  I don't think we need the earlier
 ones any more.  In any case, I accidentally added this one,
 ``trac4000_fmpq_poly_c.2.patch``.
