CORBA-ORBit compile error on DEC Unix 4.0f

[Gnanasekaran Thoppae <gnana gsf de>]

Hello,

I am trying to compile CORBA-ORBit perl module on Tru64 Unix 4.0F,
but I have a problem. I have compiled ORBit-0.5.8 on the same machine
and it works fine.

What could the problem?

Here is the compile trace:
