+# Hints for the PowerUX operating system running on Concurrent (formerly
+# Harris) NightHawk machines.  Written by Tom.Horsley@mail.ccur.com
+#
+# Note: The OS is fated to change names again to PowerMAX OS, but this
+# PowerUX file should still work (I wish marketing would make up their mind
+# about the name :-).
+#
+# This config uses dynamic linking and the Concurrent C compiler.  It has
+# been tested on Power PC based 6000 series machines running PowerUX.
+
+# Internally at Concurrent, we use a source management tool which winds up
+# giving us read-only copies of source trees that are mostly symbolic links.
+# That upsets the perl build process when it tries to edit opcode.h and
+# embed.h or touch perly.c or perly.h, so turn those files into "real" files
+# when Configure runs. (If you already have "real" source files, this won't
+# do anything).
