 <para>The Findutils package is quite old and it has problems compiling
 against newer Glibc versions (Glibc-2.0.x and up). You need to apply the
-patch that fixes some variable conflicts you'd otherwise end up
-with:</para>
+patch which fixes the following issues:</para>

+<itemizedlist>
+<listitem><para>Findutils declares a function called basename, but this
+function name is already used by the C standard libraries. This patch
+changes the Findutils version of basename function so that it is called
+basename2 instead.</para></listitem>
+
+<listitem><para>Findutils uses an incorrect way to use library files. It
+declares library functions, to tell the compiler what the name of the
+function will be when the libraries are linked in. This syntax is invalid
+and causes compiler warnings/errors. This patch removes this improper
+syntax.</para></listitem>
+
+<listitem><para>Every GNU package is supposed use a macro called _GNU_SOURCE.
+This macro enables declarations of GNU library extension functions and so the
+compiler will be able to detect name conflicts between functions more easily.
+This patch adds this macro to the source code.</para></listitem>
