Problem on HPUX 11.23 using gcc 3.4.3

[Alberto Iribarren <albertoi@xxxxxxxxxxxxxxxx>]

Hi:

I am porting an application on HPUX B.11.23 IA64 using gcc 3.4.3 (gcc
downloaded from HP site).
An error happens in any source file that includes the file
"/usr/include/sys/ipc.h" .
The error is:
/usr/include/sys/ipc.h:51: error: 'cid_t' does not name type

Compiling this source code it occurs too, using both gcc and g++:

#include <stdio.h>
#include <sys/types.h>
#include <sys/ipc.h>

int main() {
    return 0;
}

In the ipc.h file there is a struct definition that has a member called
cid. This member is a type "cid_t" variable. 
The problem is that "cid_t" is not defined. And I don't know what to
define (using -D option).

Thanks.
