engine structure, and some ANSI C compilers will complain otherwise.

For performance reasons, it is also recommended to make the (mmap'ed)
shared library 'read-only'.
-> New permissions for installed shared libraries = 555

This doesn't hurt anybody, provided the installation is performed with
'cp -f' :-)

"-Wl,+s" instead of +s:
* Hardcoded necessary references to -ldld/-ldl into the build rules and

HP-UX records the pathnames of dependent libraries when the shared libs
are built, so that ./libcrypto.sl... is recorded in libssl.sl..., with
"./" not being resolvable when running an application linked against -lssl:
* Build libssl without explicit reference to libcrypto, applications will
  be linked with "-lssl -lcrypto" anyway.
