-  # This actually depends on Xcode 4.2 or newer, not Lion per se, as it will
-  # work on Snow Leopard running Xcode 4.2. This software uses the string

-  # Note that someone could add implementations of these to str.c in this
-  # software and likely get it to compile across versions, if someone had the
-  # energy to attempt this.
