+    cc-fullversion
+	cc-fullversion is useful when the exact version of gcc is needed.
+	One typical use-case is when a specific GCC version is broken.
+	cc-fullversion points out a more specific version than cc-version does.
+
+	Example:
+		#arch/powerpc/Makefile
+		$(Q)if test "$(call cc-fullversion)" = "040200" ; then \
+			echo -n '*** GCC-4.2.0 cannot compile the 64-bit powerpc ' ; \
+			false ; \
+		fi
+
+	In this example for a specific GCC version the build will error out explaining
+	to the user why it stops.
