The former is very nice - I wish it were available in the Reiser "cpp"
that comes with just about every UNIX under the sun.  The latter is actually
in the most recent standard, if the S5 man page CPP(1) is considered the
most recent standard (it also documents __FILE__ and __LINE__).  The
parentheses are optional (shades of the "return(x)" vs. "return x" debate!)
according to CPP(1).
