 I see.  I tested under -current and FreeBSD lint doesn't give the
 syntax error there.  This is a bug in -current.  FreeBSD lint now uses
 "/usr/bin/cc -E x c -D__attribute__(x)= ..." for the preprocessor
 instead of the correct /usr/bin/cpp (in it 4.3 uses /usr/libexec/cpp
 which is correct there).  Using cc instead of cpp results in __GNUC__
 and possibly other wrong things being defined.  This would break all
 programs that carefully use "#ifdef __GNUC ...", except some of the
 breakage is worked around by defining away __attribute__(x).  But
 defining away __attribute__(x) mainly breaks lint's detection of use
 of this unportable feature.
