 * Use <code>make all 7z-dist</code>, <code>make all tar-dist</code> or <code>make all zip-dist</code> instead of <code>make all nsis-installer</code> if you want to build just an archive of the files to install on MS Windows instead of an installer wizard.
-* By default, packages will be built one at a time, but you may use <code>make JOBS=4</code> (choose a number other than 4 that is appropriate for your system) to build each package in parallel.  You may also combine this with the <code>-j</code> option for Make to build more than one package at a time, but be careful as using <code>make -j4 JOBS=4</code> can result in as many as 16 jobs running at once.
+* By default, packages will be built one at a time '''without parallelization'''. You may use <code>make JOBS=4</code> (choose a number other than 4 that is appropriate for your system) to build each individual package in parallel.
+** '''Avoid using the <code>-j</code> option for <code>make</code>:''' Using <code>-j</code> enables building packages in parallel, which can mess up the mxe build system.  Use this option with care!  Another pitfall is the example <code>make -j4 JOBS=4</code>, which can result in as many as 16 jobs running at once.
 * Include gdb in the installer by running <code>make gdb</code> before making the <code>nsis-installer</code> target.
