Yes, you will have to be careful before you use them. The SDK compatibility guide specifies how, but basically you just check if the address of a function is non-NULL before calling it.

The entire point of the deployment target is to allow for you to use a newer SDK (and optionally newer APIs) while targeting an older OS. You won't be able to build on Leopard with SDKs newer than 10.5, but you can run binaries that do.

But the plugin package also contains the resource file created by "rez". That need a parameter "-isysroot /Developer/SDKs/MacOSX10.5.sdk" specified for example. But the 64-bit version must be compiled with SDK 10.6, right? I mean Leopard wasn't 64-bit. And I still want to maintain compatibility with Leopard for 32-bit version, so I need to 10.5 SDK, so how to do that?? Or can I use 10.5 for both cases?
Unless you are trying to target 64-bit PowerPC, you don't need the 10.5 SDK, just use the 10.6 SDK and set the deployment target for 10.5.
