+NOTE: Oracle Solaris users need to download/compile the TAP driver from http://www.whiteboard.ne.jp/~admin2/tuntap/
+
+The generated binaries _may_ work on Solaris 2.10 or earlier, you're on your own. (Recommended: `-static-libstdc++ -static-libgcc`, and the TAP driver if not already installed on the target system.)
+
+Building on a v2.10 or earlier system is unsupported, and may not even work; recent GCC releases have progressively dropped support for older system releases.
