OK, I'm in much better shape now. My project has a completely new
project file. I suspect that the previous project file was converted
from CW9 (back in the days of PB or early xcode). Even after
converting that, I still had random occurrences of 'Cannot find
symbol'. That appears to have been caused by running ~600 class
definitions in the default package. All my source files (excepting the
one containing main) are now in a named package, and appear to be
compiling (and executing) happily.
