commit 4928a3fe2bde9046d9e9a327200a08c5a345002b
Author: Felix Salfelder <salfelder at em.cs.uni-frankfurt.de>
Date:   Thu Jan 26 21:34:21 2012 +0100

    a callback for sage
    
    (from sage-4.7.tar/spkg/ntl/dist/debian)
    
     We add a SetErrorCallbackFunction(). This sets a global callback function _function_,
     which gets called with parameter _context_ and an error message string whenever Error()
     gets called.
    
     Note that if the custom error handler *returns*, then NTL will dump the error message
     back to stderr and abort() as it habitually does.
