+#----------------------------------------------------------------
+# QNX hints
+#
+# As of perl5.003_09, perl5 will compile without errors
+# and pass almost all the tests in the test suite. The remaining
+# failures have been identified as bugs in the Watcom libraries
+# which I hope will be fixed in the near future.
+#
+# As with many unix ports, this one depends on a few "standard"
+# unix utilities which are not necessarily standard for QNX.
+#
+# /bin/sh  This is used heavily by Configure and then by
+#          perl itself. QNX's version is fine, but Configure
+#          will choke on the 16-bit version, so if you are
+#          running QNX 4.22, link /bin/sh to /bin32/ksh
+# ar       This is the standard unix library builder.
+#          We use wlib. With Watcom 10.6, when wlib is
+#          linked as "ar", it behaves like ar and all is
+#          fine. Under 9.5, a cover is required. One is
+#          included in ../qnx
+# nm       This is used (optionally) by configure to list
+#          the contents of libraries. I will generate
+#          a cover function on the fly in the UU directory.
+# cpp      Configure and perl need a way to invoke a C
+#          preprocessor. I have created a simple cover
+#          for cc which does the right thing. Without this,
+#          Configure will create it's own wrapper which works,
+#          but it doesn't handle some of the command line arguments
+#          that perl will throw at it.
+# make     You really need GNU make to compile this. GNU make
+#          ships by default with QNX 4.23, but you can get it
+#          from quics for earlier versions.
+#----------------------------------------------------------------
+# Outstanding Issues:
+#   lib/posix.t test fails on test 17 because acos(1) != 0.
+#      Watcom promises to fix this in next release.
+#   lib/io_udp.t test hangs because of a bug in getsockname().
+#      Fixed in latest BETA socket3r.lib
+#   If there is a softlink in your path, Findbin will fail.
+#      This is a documented feature of getpwd().
+#   There is currently no support for dynamically linked
+#      libraries.
+#----------------------------------------------------------------
+# At present, all QNX systems are equivalent architectures,
+# so it might be reasonable to call archname=qnx rather than
+# making an unnecessary distinction between AT-qnx and PCI-qnx,
+# for example.
