I know what the problem is; as I was saying, I didn't find a way to get
past this type of error except "don't do that", i.e. break down what cpp
is seeing into manageable bites.
How about the attached work-around (obviously '#if 1' should be changed
to something more like '#if using-the-hp-ux-cc-compiler')?
(Build succeeds with this, using HP-UX's cc. I'll post the test results
when the suite is done.)
