I posted a question about this recently and got an answer for the Sun, at
least.  Jim Litchfield sent me the answer (Thanks, Jim!).  It's a bug in cpp
that can be worked around by running cpp separately, and then cxref.  I use the
following script:

#! /bin/csh
foreach name (*.c)
/usr/lib/cpp -Dunix -Dsun -Dsparc $name >${name:r}.cref.c
end
cxref -cst -o rpe.cref *.cref.c 
foreach name (*.cref.c)
\rm $name
end

To find out what options to pass the compiler, do a cc -dryrun.  The bug is
supposedly fixed in 4.1.
