What's "this" above?

I would have expected the cross-compiler to have some define that says
you're compiling for HP/UX so that you change your code using preprocessor.
If it's not possible, then you'd have to set your own define manually,
when building for HP/UX. I don't think autoconf can run a binary for
target system to check run-time properties, even if you have the target
system around.

Anyway, is your point that autoconf is also problematic, or what?
