+*** Installing to a directory with spaces in the name fails.
+
+For example, if you call configure with a directory-related option
+with spaces in the value, eg --enable-locallisppath='/path/with\ spaces'.
+Using directory paths with spaces is not supported at this time: you
+must re-configure without using spaces.
+
+*** Installing to a directory with non-ASCII characters in the name fails.
+
+Installation may fail, or the Emacs executable may not start
+correctly, if a directory name containing non-ASCII characters is used
+as a `configure' argument (e.g. `--prefix'). The problem can also
+occur if a non-ASCII directory is specified in the EMACSLOADPATH
+envvar.
+
+*** On Solaris, use GNU Make when installing an out-of-tree build
+
+The Emacs configuration process allows you to configure the
+build environment so that you can build emacs in a directory
+outside of the distribution tree. When installing Emacs from an
+out-of-tree build directory on Solaris, you may need to use GNU
+make. The make programs bundled with Solaris support the VPATH
+macro but use it differently from the way the VPATH macro is
+used by GNU make. The differences will cause the "make install"
+step to fail, leaving you with an incomplete emacs
+installation. GNU make is available in /usr/sfw/bin on Solaris
+10 and can be installed as /opt/sfw/bin/gmake from the Solaris 9
+Software Companion CDROM.
+
+The problems due to the VPATH processing differences affect only
+out of tree builds so, if you are on a Solaris installation
+without GNU make, you can install Emacs completely by installing
+from a build environment using the original emacs distribution tree.
