The following reply was made to PR bin/29675; it has been noted by GNATS.

It does give me the syntax error, > which causes all my lint's to fail. 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.
