I am very surprise that they have sigaction without the
sa_sigaction member. Anyways, it looks like you can't do the
mem_fault_handler, so just replace the line:

         sa.sa_sigaction= mem_fault_handler ;

with this:

         sig_handler = general_handler ;

Then delete these two lines immediately below:

         sig_handler = NULL ;
         sa.sa_flags = SA_SIGINFO ;

That should solve your problem. I guess the tests in configure
will need to be updates not to assume sa_sigaction exists if the
sigaction function does.
