[libvirt] FreeBSD and sys/syslimits.h

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? Matthias
