Comment (by kencu):

 {{{__MAC_OS_X_VERSION_MIN_REQUIRED}}} is something Jeremy often wanted to
 use, and he was around a lot at that time.

 It is defined on Leopard and newer, and also is defined on any Tiger port
 that is using legacysupport, as I added it to that.

 In general, we should just use {{{MAC_OS_X_VERSION_MIN_REQUIRED}}} instead
 -- but I didn't want to keep changing Jeremy's patches to that, so I left
 it most often.

 Regarding {{{AI_NUMERICSERV}}} -- I'm not really certain that defining it
 (to a made-up value of zero or any other number) is a good idea on systems
 that don't actually support that functionality.

 For example, once you define {{{AI_NUMERICSERV 0}}} then a later block of
 code looking to see if it should use {{{AI_NUMERICSERV}}} by seeing if it
 is defined to something will see that it is defined, and so use it -- and
 this is plain wrong.
