The warning only tells you that the program may possibly not run on a
PA-RISC1.1 machine. It's harmless, though rather annoying, if you don't
have to worry about PA-RISC1.1. The compile and link did succeed and
you should be able to run your program normally.

The problem with GCC "fixing" up includes is that it creates a stronger
than necessary dependency on the version of the OS. Since GCC was
configured for HP-UX 11.11, I presume that it was also built on HP-UX
11.11 and thus that the "fixed" headers it includes are those belonging
to HP-UX 11.11. Installing this compiler on HP-UX 11.00 is not without
its challenges, if it is possible at all...

I fear there's no easy solution. If you're up to it, I would suggest
building GCC on your machine so that the headers match.

Hope this helps,
