There are the SDKs, but that doesn't "check" for compatibility; that
compiles the target against the library & framework headers of the old
OS. And even that doesn't guarantee compatibility; as I found out the
hard way a while ago, if your target links against any third-party
libraries that were not built against the same SDK, then you still run
the chance of the application not working in the older OS releases.
I tried not to do anything Panther-specific,
but evidently something slipped in; the program works on Panther
machines but not my friend's Jaguar machine.
You should always check for messages in the console when this happens,
because launch problems are always reported in the console rather than
being displayed to the user. So ask your friend to launch Console.app
(in /Applications/Utilities), attempt to run the application, and see
if anything appears in the console.
