The patch

http://gcc.gnu.org/ml/gcc-patches/2005-03/msg00712.html

causes more than 1000 failures:

The problem seems uniuqe to ia64. The good ones:

Even if ld sees natLogger.o first, the definitions in Logger.o will be used.
The bad ones are

The ones in Logger.o will be discarded. The problem may 
be .L_ZN4java4util7logging6Logger7getNameEv13. Discarding definitions in 
Logger.o seems to cause problems on ia64.
