+ * Debugging macros, DUK_DPRINT() and its variants in particular.
+ *
+ * DUK_DPRINT() allows formatted debug prints, and supports standard
+ * and Duktape specific formatters. See duk_debug_vsnprintf.c for details.
+ *
+ * DUK_D(x), DUK_DD(x), and DUK_DDD(x) are used together with log macros
+ * for technical reasons. They are concretely used to hide 'x' from the
+ * compiler when the corresponding log level is disabled. This allows
+ * clean builds on non-C99 compilers, at the cost of more verbose code.
+ * Examples:
+ *
+ * DUK_D(DUK_DPRINT("foo"));
+ * DUK_DD(DUK_DDPRINT("foo"));
+ * DUK_DDD(DUK_DDDPRINT("foo"));
+ *
+ * This approach is preferable to the old "double parentheses" hack because
+ * double parentheses make the C99 solution worse: __FILE__ and __LINE__ can
+ * no longer be added transparently without going through globals, which
+ * works poorly with threading.
