The discussion on 2008-11-05 led to an agreement how to best fix this, but
no one actually committed the fix. Now done as follows:
2008-12-22 Ingo Weinhold <ingo_weinh...@gmx.de> (tiny change)
Eric Blake <e...@byu.net>
Paolo Bonzini <bonz...@gnu.org>
Bruno Haible <br...@clisp.org>
Make c-stack work on Haiku.
* lib/c-stack.c (SA_ONSTACK): Define fallback.
(c_stack_action): Use SA_ONSTACK flag.
