Description Lyndon Nerenberg 2000-08-18 21:20:00 UTC 
/usr/libexec/cpp doesn't support the -undef flag, although --help
documents it. (As does the cpp(1) manpage, although it's unclear
if cpp(1) is meant to apply to /usr/libexec/cpp as well as the
one in /usr/bin.)

lcc (/usr/ports/lang/lcc) invokes /usr/libexec/cpp with -undef, and
thus breaks when /usr/libexec/cpp barfs about the unrecognized option.

Fix: 

Re-enable -undef for the cpp in /usr/libexec.
How-To-Repeat: 
Install lcc from ports, then try to compile something.

-undef is not needed with the new libexec/cpp designed just for compiler's 
use.  Fix committed to the lcc port.
