[libvirt] FreeBSD and sys/syslimits.h

[Matthias Bolte <matthias bolte googlemail com>]

libvirtd.h includes sys/syslimits.h if available. On FreeBSD the
header contains this warning:

In file included from libvirtd.h:42,
                 from dispatch.h:28,
                 from dispatch.c:30:
/usr/include/sys/syslimits.h:41:2: warning: #warning "No
user-serviceable parts inside."

Here's the relevant part from that header:

#if !defined(_KERNEL) && !defined(_LIMITS_H_) && !defined(_SYS_PARAM_H_)
#ifndef _SYS_CDEFS_H_
#error this file needs sys/cdefs.h as a prerequisite
#endif
#ifdef __CC_SUPPORTS_WARNING
#warning "No user-serviceable parts inside."
#endif
#endif

This looks like this header is not meant to be included directly, at
least on FreeBSD.

Is this something gnulib or libvirt should care about?
