+#  - the dependency tracking uses -MD in order to avoid needing an
+#    explicit `make depend' step
+#  - the definition of CFLAGS includes the gcc-specific flag
+#    `-Wall'
+#
+# Currently depends on GNU make, because:
+#  - the Makefile uses GNU ifdef / ifndef commands and GNU make `%'
+#    pattern rules
