+# The original 'makefile' has a flaw:
+# 1) it overrides CFLAGS
+# 2) it does not pass extra "FLAGS" to $(CC) that could come from environment
+#
+# It means :
+# - we need to edit 'makefile' for different builds (DEBUG, etc...), which is
+#   not practical at all.
+# - Also, it does not allow to run all tests without editing the test source
+#   code.
+#
+# To use this makefile (GNU make only):
+# 1) copy it into exercise directory
+# 2) add ex.h to exercise include file
+# 3) add ex.c to exercise source code, and create a suitable main function
+# 4) use make with one of the following targets :
+#   all: compile and run all predefined tests.
+#   nowarn: compile with no -Werror, and run all predefined tests
+#   debug: compile with -DDEBUG and run all predefined tests
+#   mem: perform memcheck with all tests enabled
+#   unit: build standalone (unit) bimary
+#   unitnowarn: build standalone (unit) binary with -Werror disabled
+#   unitdebug: build standalone binary with -DDEBUG
+#
+# Original 'makefile' targets can be used (test, memcheck, clean, ...)
