Apple includes AvailabilityMacros.h for targeting OS versions with MAC_OS_X_VERSION_MIN_REQUIRED & MAC_OS_X_VERSION_MAX_ALLOWED macros. This header has been a part of Darwin since 6.x (OS X 10.2) and a more recent Availability.h for API availabilty based on targeted OS version (which OS version an API was introduced & deprecated), since Darwin 9 (OS X 10.5).
A common idiom is to do an ifdef dance for _APPLE_ && _MACH_ before including these headers. Could autoconf probe for them by default and provide a symbol since they are a standard part of the OS and have been around for some time. It would make it easier for autoconf users & folks who package for Darwin to patch software.
