Yes, I use the OpenSSL callbacks (hopefully correctly). I took the
openssl example under the link you provided and replaced their thread
working function with function from https.c to fetch https pages.

Sorry for confusing, I meant that -D_THREAD_SAFE helped me to make my
test program run on AIX. I do not think this will help on HP-UX. Could
there be any other similar issue?

You you set the OpenSSL callbacks?

Hm, I wonder if we should set this define by default... Currently this
is only
set for AIX builds and now you say HPUX needs it as well...
