Take a look at the equivalent in CodeWarrior, the function called
__LoadAndRelocate__() in PalmOS_Startup.c. It calls DmGet1Resource() to
recover the code segment handles to be unlocked. (And I sure hope that CW
multi segment apps are ROMable!) Would this work in GCC?

The problem with using DmGet1Resource here, is that if an app failed to
close some resource database that it had opened before exiting (SysAppExit
normally cleans this up, but later), then DmGet1Resource will fail to get to
the app's own database and will not find the requested handle (or equally
bad, might find a resource of the same type/id in the wrong database).
