Comment (by ken.cunningham.webuse@…):

 When testing these availability macros for another trac issue, it appeared
 to me that MAC_OS_X_VERSION_MAX_AVAILABLE best defines the system you're
 currently building on.

 I know MAC_OS_X_VERSION_MIN_REQUIRED is listed as a test on various
 websites for system testing as well, and I have read those -- and
 admittedly it is still confusing to me at times despite an evening looking
 it over, but ultimately it appears that MAC_OS_X_VERSION_MIN_REQUIRED does
 not reliably represent the machine you're building on, as in this case.

 Defer to experts. Jeremy has written on this topic not long ago in these
 pages, I know.
