What's sadder is we should have already known this.  The ChangeLog for
c-stack.c referred to this link:
http://mail.gnu.org/archive/html/bug-textutils/2003-03/msg00027.html

Looks like Bruno needs to add a row to libsigsegv's PORTING file.

It may be that you are tripping over this bug in libsigsegv 2.5, but fixed
in CVS:
http://lists.gnu.org/archive/html/bug-gnulib/2008-07/msg00073.html

At any rate, I'm still working on a patch that makes lib/signal.in.h add
the #define for sa_sigaction if HAVE_SIGACTION &&
!HAVE_STRUCT_SIGACTION_SA_SIGACTION.  I'll post a snapshot for you to try
once I get it completed.
