[omniORB] omniidl compile of ir.idl failing on ia64 HP-UX 11.23

[Brian McNamara]

I am attempting to build omniORB-4.0.6 on an HP Itanium box running HP-UX
11.23 (11i v2).  Everything works fine until I get the following error when
omniidl attempts to compile the ir.idl file:

It appears that the omnicpp precompiler is not finding the following
#include on line 6 of ir.idl:
#include <corbaidl.idl>

This file does exist in the "../../../../idl" directory which is specified
in the list of -I directories for omnicpp.

The omnicpp does find corbaidl.idl if I change the include to use quotes:

#include "corbaidl.idl"

However, I don't think that is the right solution.

Thank you for any help you can give.
