+================
+  HP-UX (11.0 / 11i):
+   The dlopen() system call in HP-UX has problems when loading/unloading
+   C++ modules. To resove the problem, use either of the following two
options:
+   (1) Recommended : Use the shl_load to do the module loading/unloading.
+
+      - Create a config.cache file in $APACHE_SRC with the following
contents:
+        ac_cv_func_dlopen=${ac_cv_func_dlopen=no}
+        ac_cv_header_dl_h=${ac_cv_header_dl_h=yes}
+        ac_cv_header_dlfcn_h=${ac_cv_header_dlfcn_h=yes}
+        ac_cv_lib_dl_dlopen=${ac_cv_lib_dl_dlopen=no}
+        ac_cv_lib_dld_shl_load=${ac_cv_lib_dld_shl_load=yes}
+
+        Using the --config-cache option with the configure, forces the use
+        of shl_load system call instead of the dlopen to load the modules. 
+
+      - Download the cpprt0_stub.s from the web site :
+
http://h21007.www2.hp.com/hpux-devtools/CXX/hpux-devtools.0107/0083.html
+
+      - Compile with the PIC option
+        cc -c +z cpprt0_stub.s
+          - OR -
+        gcc -c -fPIC cpprt0_stub.s
+
+      - Continue using dlopen, and link the httpd binary with
+        "cpprt0_stub.o -lcl"
+
+    (2) Link httpd with "cpprt0_stub.o -lcl -lCsup"
+
+  HP-UX (11i version 1.5 and greater):
+    Link httpd with "cpprt0_stub.o -lcl -lunwind"
