I didn't see the beginning of this thread, so I may be answering a question
that wasn't asked.
You can overcome problems created when Apple omits availability macros from
functions in headers, simply by re-declaring them in your own headers with
the required availability macros.
For example, when building an accessibility app in Panther that also has to
run in Jaguar without the new Panther feature, I include the following
before my @interface directive:
extern AXError AXUIElementCopyParameterizedAttributeNames (AXUIElementRef
element, CFArrayRef *names) AVAILABLE_MAC_OS_X_VERSION_10_3_AND_LATER;
I also have to wrap the function call in an if block like so:
if ( AXUIElementCopyParameterizedAttributeNames ) {
// function is available on this system
// so call the function here
}
