+Configuring threads
+-------------------
+
+The main switch to configure threads is to run the configure script
+(see below) with the --with-thread switch (on DEC, use
+--with-dec-threads).  Unfortunately, on some platforms, additional
+compiler and/or linker options are required.  Below is a table of
+those options, collected by Bill Janssen.  I would love to automate
+this process more, but the information below is not enough to write a
+patch for the configure.in file, so manual intervention is required.
+If you patch the configure.in file and are confident that the patch
+works, please send me the patch.  (Don't bother patching the configure
+script itself -- it is regenerated each the configure.in file
+changes.)
