While strange, this should not cause any major problems. It should just
disable the use of zlib in the build. If you want to fix it, investigate the
config.log and see what test program that failed and then try to see why it
fails.

Clearly lib/file.c is not including the correct system header for the fd_set
type for you. I'm a bit surprised, since (lib)curl has built on HPUX for ages.

Currently my HPUX test server is inaccessible so I can't verify that it still
builds.

Can you try editing the include/curl/curl.h header at around line 154 to make
sure it includes <sys/select.h> for you and see if it helps? The comment there
says you shouldn't have thad header...

I googled on this, and found indications that <sys/time.h> would be the one to
use for select() on HP-UX 11, and as far as I can see that is already
included!
