Yeah, that's because versions before 10.5 aka darwin 9 aka "Leopard" have a
broken iconv implementation.

I've got my information from [1]. It says:

darwin 1.3 => OSX 10.0
darwin 1.4 => OSX 10.1
darwin 6 => OSX 10.2
darwin 7 => OSX 10.3
etc.

I don't know why they chose this weird versioning scheme, but wait, it gets
even crazier

darwin 1.4.1 => OSX 10.1
darwin 5.1 => OSX 10.1.1

So my patch checks only for 10.1 but not for 10.1.1 *sigh*

-     NO_STRLCPY = YesPlease
+     ifeq ($(shell expr "$(uname_R)" : '[015]\.'),2)
+             NO_STRLCPY = YesPlease
+     endif

Should get all darwin versions before 6.0 in which strlcpy(3) was
introduced. Thanks for your patience ;)
