This has come as a surprise to many of us, who have now more or less
unwittingly put Jaguar-crippled apps on the market. And it also apparently
prevents an app from running on any version of Panther earlier than 10.3.9.

Read the "About Xcode Tools" document. It explains that apps built with the
gcc 4 compiler will only run on 10.3.9 and newer. You have to build with the
gcc 3 compiler to get Jaguar and early-Panther compatibility, even though
you have used the correct cross-development SDKs and build settings.

I, for one, plan to release ".1" versions of my products with Jaguar and
early-Panther compatibility restored -- at least after Apple releases Tiger
10.4.1.
