The 32-bit runtime must remain binary compatible with all code that was compiled and targeted for Tiger and earlier.

It is extremely desirable to be able to link against the 10.5 SDK and still deploy your application on Tiger (after taking appropriate measures.)

Huh? I thought the point of linking against a new SDK was to take advantage of features in that SDK, not to maintain backwards compatibility with the older OS features?

Suppose there is a new framework feature on Leopard that I want to take advantage of. I link against the 10.5 SDK and in my code d


if (some feature available) {

} else {
	... some alternate code, or nothing at all ...
}

The resulting binary can, with care, still work on 10.4 and earlier.
