epan/configure.in checks for dlopen but not shl_load (dlopen
equivalent on HP-UX). Nowhere in epan/* is dlopen used though (you use
the Glib equivalent). And, Glib 1.2.x supports shl_load under HP-UX.
So, the patch below allows Ethereal to build on HP-UX 10.20 (it worked
fine as-is under 11.00).
Note we also check for shl_load in the top-level configure though it's
never used. Feel free to reject it. I note that dlopen is used only
under Linux in packet-snmp.c
Using internal autoconf variables is probably not a good idea:
if test "$ac_cv_header_dlfcn_h" = yes ; then
AC_DEFINE(HAVE_PLUGINS)
fi
