I have trouble with compiling GCL on HP.

I am running on 9000/735 machine ruuning HP-UX 09.05.

So I did add-defs hp800 (from  MACHINES). Everything compiles fine.
However when LISP initializes I get:

How do I have to define this macro?

The macro GCL uses to test whether a variable is on the C stack
is incorrect. If you find the definition for that macro (it has
the name NULL_OR_ON_C_STACK, I believe) you need to change it
to reflect the way a process is actually laid out in HP-UX 9.x.
The stack region is 0x7b033000-0x7ffe6000.
