[Dev] status of full build on Tiger / gcc 4.0

[Andi Vajda]

I'm happy to report that the issues preventing a full external/internal build 
from building and running on Mac OS X 10.4 / gcc 4.0 have been resolved.
Chandler is up and running (not any faster or slower in a detectable way).

To do a full build on Tiger / gcc 4.0 (in addition to the usual procedure):
   - make sure that gcc 4.0 is your default compiler by running 'gcc --version'
     and switching with gcc_select if needed
   - set GCJ_VER to 4 in external/Makefile.inc
   - build gcc 4.1 from the most recent snapshot (like 20050501) following the
     instructions in PyLucene/INSTALL (for PyLucene)
   - set GCJ_HOME to the value you chose for --prefix when configuring the gcc
     build
