+# 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.
+#
+# I hope this will be use-able for next exercises...
