Evidently, you need to include another header before sys/ipc.h, namely
the one that defines the cid_t type. Care to find out which one that
is?

So where is cid_t defined?

So where is cid_t defined?

/usr/include/sys/types.h: typedef int32_t cid_t; /* For compartment IDs */

This is 8.1beta1.

I see sys/ipc.h already #includes sys/types.h, though.

Possibly there's some magic #define needed to expose the cid_t
definition?

We have this in src/template/hpux
CPPFLAGS="-D_XOPEN_SOURCE_EXTENDED"
because it seems necessary on HPUX 10. It used to work on HPUX 11 too,
the last time I tried that ...

Here's my 11.23 compile line:
gcc -O2 -mlp64 -Wall -Wmissing-prototypes -Wpointer-arith
-Wendif-labels -fno-strict-aliasing -I../../../src/include
-D_XOPEN_SOURCE_EXTENDED -c -o pg_sema.o pg_sema.c

I've attached sys/types.h and sys/ipc.h. I'm happy to try any
patches you suggest...

The problem is obviously impossible given those headers ;-).

What seems most probable at this point is that gcc is not looking at
the headers you think it is. gcc keeps private "fixed" copies of
system headers that it thinks are broken. I suspect that your gcc
installation was copied from an earlier HPUX version that had different
contents of one or both of these headers.

I'm not sure if you need to completely reinstall gcc to fix this,
or if just rerunning its fixincludes script will do the job. Or
you could try manually updating the private copies, but that seems
pretty risky. In any case I think it's a gcc-doesn't-match-system
problem, not our bug.
