I guess I am partially responsible for this, the header directories
/usr/include and /usr/local/include should be searched in the same order
that the loader searches the corresponding library directories /usr/lib
and /usr/local/lib.  The following patch to cccp.c will provide more
reasonable behavior, and behavior which will not break in the event that
strange stuff has been deposited in /usr/local/include.
Having the C++ headers in /usr/local/include instead of a C++ specific
directory is a bad idea, however.  These should be in /usr/include/CC or
/usr/local/include/CC.
