Subject: Cyclic dependency between <sys/ucontext.h> and <ucontext.h>
Date: Fri, 14 Feb 2003 21:31:00 -0000	[thread overview]
Message-ID: <jeof5esg5q.fsf@sykes.suse.de> (raw)

There is a cyclic dependency between the headers <sys/ucontext.h> and
<ucontext.h> when _XOPEN_SOURCE is defined to 500 or 600: <sys/ucontext.h>
includes <signal.h> which includes <ucontext.h> which includes
<sys/ucontext.h>.  The effect is that you'll get a compiler error when
including <sys/ucontext.h> due to ucontext_t begin undefined.  I don't
know how to fix that properly, a workaround is to include <ucontext.h>
instead.

Andreas.
