+The legacy method to build 32 bit wine on x86_64 will will require
+a multilib installation.
+
+Please read up alienBOB's multilib readme and repo:
+
+https://docs.slackware.com/slackware:multilib
+http://www.slackware.com/~alien/multilib/
+
+A script that rsyncs with alienBOB's repo and installs the multilib
+packages which can be found here:
+
+https://slackware.uk/~dive/scripts/alien-multilib-rsync.sh
+
+Be sure to read the short instructions at the top.  If you use slackpkg
+then you will also want to blacklist his packages in
+/etc/slackpkg/blacklist:
+
+[0-9]+alien
+[0-9]+compat32
+
+If you have a combined 32 and 64 bit package you need to set the
+environmental variable WINEPREFIX to point to the 64 bit wine directory
+when running wine64, which should be different to the 32 bit directory
+(~/.wine by default).
+
+Example:
+
+WINEPREFIX=~/.wine64 wine64 notepad
+
+To build wine using the legacy method, pass MULTILIB=yes to the build
+script.
