I am unable to reproduce this bug on my 9000/345
uname -a says
HP-UX davesys 7.0 B 9000/375 davesys

Box says 9000 345.

cc -v -O ccbug.c 
ccbug.c:
        /lib/cpp  ccbug.c /tmp/ctm4DAAa05103
        /lib/cpass1  -Yo /tmp/ctm4DAAa05103 /tmp/ctm1AAAa05103
"ccbug.c", line 7: warning: incorrect combination of pointer and integer, op =
        /lib/c1  /tmp/ctm1AAAa05103 /tmp/ctm2BAAa05103
        /lib/cpass2  /tmp/ctm2BAAa05103 /tmp/ctm5EAAa05103
        /lib/c2  /tmp/ctm5EAAa05103 /tmp/ctm3CAAa05103
        /bin/as20  -o ccbug.o /tmp/ctm3CAAa05103
/bin/ld  /lib/crt0.o ccbug.o -x -lc


Everything OK.  
This must be a 800 series problem

I have no Idea where to get the "Compiler ID" from
