if I remember corretly with C99 if you do s.th. like this (simple
sample):

#define LOG(level, format, ...)					\
                log(level, format, ##__VA_ARGS__);

you _need_ to give an argument:

	LOG(debug, "blah", 0);

w/o the ", 0" this is an error.

There have been gcc extentions that allow(ed) zero arguments.

*searching*
