+
+	Remove obsolete HAVE_STDINT_H probing macro.
+
+	This macro was updated by the unix configure script and the
+	`CMakeLists.txt' one, but is never used in the source tree (nor is
+	<stdint.h> included anywhere).
+
+	* CMakeLists.txt, builds/unix/ftconfig.in: Don't handle

 	Remove Jamfile files from the tree.
