+=head2 Outstanding Issues with Perl on QNX4
+
+There is no support for dynamically linked libraries in QNX4.
+
+If you wish to compile with the Socket extension, you need
+to have the TCP/IP toolkit, and you need to make sure that
+-lsocket locates the correct copy of socket3r.lib. Beware
+that the Watcom compiler ships with a stub version of
+socket3r.lib which has very little functionality. Also
+beware the order in which wlink searches directories for
+libraries. You may have /usr/lib/socket3r.lib pointing to
+the correct library, but wlink may pick up
+/usr/watcom/10.6/usr/lib/socket3r.lib instead. Make sure
+they both point to the correct library, that is,
+/usr/tcptk/current/usr/lib/socket3r.lib.
+
+The following tests may report errors under QNX4:
+
+ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give
+the same results. cwd calls `fullpath -t`, so if you
+cd `fullpath -t` before running the test, it will
+pass.
