I don't find it better, actually I think it's much harder to read.

Maybe that's just me.

Call me extremist, but I think I could even like the following :-)

#define   CWARN(format, ...)	CDEBUG_LIMIT(D_WARNING,  format, ## __VA_ARGS__)
#define  CERROR(format, ...)	CDEBUG_LIMIT(D_ERROR,    format, ## __VA_ARGS__)
#define CNETERR(format, ...)	CDEBUG_LIMIT(D_NETERROR, format, ## __VA_ARGS__)
#define  CEMERG(format, ...)	CDEBUG_LIMIT(D_EMERG,    format, ## __VA_ARGS__)
