a message like the one below:

g++ -c -O -pipe -I/usr/include/g++-include -I. -I/usr/local/include/pccts -o cccc.o cccc.cpp
cccc.cpp: In method `void CParser::start(class ASTBase **)':

cccc.cpp:47: (Each undeclared identifier is reported only once
cccc.cpp:47: for each function it appears in.)

My guess is that this one was left behind after the pccts upgrade.
something already there (PORTOBJFORMAT, OSVERSION) or move stuff from after
.include <bsd.port.mk> to before.
(This is not by any means the complete list but just the ones I've noticed
recently.)
