This compiles fine on OSX too. :)
One niggle with it though... this is what is looks like in context:
*******************************************************************
...
#include "virerror.h"
#include "virfile.h"
#define VIR_FROM_THIS VIR_FROM_SYSTEMD
VIR_LOG_INIT("util.systemd");
#ifndef MSG_NOSIGNAL
# define MSG_NOSIGNAL 0
#endif
static void virSystemdEscapeName(virBufferPtr buf,
const char *name)
{
static const char hextable[16] = "0123456789abcdef";
#define ESCAPE(c)
...
*******************************************************************
Isn't it kind of crying out for a useful comment, so the next person
looking through this code has a good chance to understand why it's
there? ;)
Maybe something like:
/* OSX is missing MSG_NOSIGNAL, so we define it here to avoid
* failure during building.
*/
:)
