 > To me that looks correct for all versions of OS X. But it does depend on
 `__MAC_OS_X_VERSION_MAX_ALLOWED`. How can I check to see what value that
 has?

 That code looks correct.  __MAC_OS_X_VERSION_MAX_ALLOWED should be
 determined by the SDK being used.

 I'd recommend just adding this to sanity check:
 {{{
 #if __MAC_OS_X_VERSION_MAX_ALLOWED >= 1060
 #error __MAC_OS_X_VERSION_MAX_ALLOWED has an unexpected value
 #endif
 }}}
