Shared library support for Solaris and HPUX

by Lutz Behnke and by Lutz Jaenicke.

Hopefully we'll have a unified way of handling shared libraries when
we move to autoconf...

+# 
+# HP-UX (10.20) shared library installation:
+# Compile and install OpenSSL with best possible optimization:
+# - shared libraries are compiled and installed with +O4 optimization
+# - executable(s) are compiled and installed with +O4 optimization
+# - static libraries are compiled and installed with +O3 optimization,
+#   to avoid the time consuming +O4 link-time optimization when using
+#   these libraries. (The shared libs are already optimized during build
+#   at +O4.)
+#
+# This script must be run with appropriate privileges to install into
+# /usr/local/ssl. HP-UX prevents used executables and shared libraries
+# from being deleted or overwritten. Stop all processes using already
+# installed items of OpenSSL.
+#
+# WARNING: At high optimization levels, HP's ANSI-C compiler can chew up
+#          large amounts of memory and CPU time. Make sure to have at least
+#          128MB of RAM available and that you kernel is configure to allow
+#          128MB data size (maxdsiz parameter).
+#          The installation process can take several hours, even on fast
+#          machines. +O4 Optimization of the libcrypto.sl shared library may
+#          take 1 hour on a C200 (200MHz PA8200 CPU), +O3 compilation of
+#          fcrypt_b.c can take 20 minutes on this machine. Stay patient.
+#
+# SITEFLAGS: site specific flags. I do use +DAportable, since I have to
+# support older PA1.1-type CPUs. Your mileage may vary.
+# +w1 enables enhanced warnings, useful when working with snaphots.
