yes, this is in fact not suitable to test for 0 args. For the
preprocessor 0 args basically doesn't exist, there is always one
argument, but which is empty.
If this is really needed, I could contribute a cooked down version
from P99 of an NARGS macro that could deal with such a case. Please
let me know.
