libjava compile warnings, top ones for sparc64-linux in current 3.3

[Christian Joensson <c dot christian dot joensson at telia dot com>]

When bootstrap/building gcc 3.3 (CVS branch Fri Mar 21 10:06:33 UTC
2003) and friends on sparc64-linux, I get the following java/libjava
warnings:

     19	libjava/java/lang/mprec.c
     12	libjava/gnu/java/nio/natSocketChannelImpl.cc
      9	java/lang/Integer.h
      8	libjava/java/lang/strtod.c
      8	libjava/java/lang/dtoa.c
      6	libjava/java/lang/e_exp.c
      4	libjava/java/lang/w_exp.c
      2	libjava/verify.cc
      2	libjava/prims.cc
      2	libjava/jni.cc
      2	libjava/java/net/natNetworkInterface.cc
      2	libjava/java/lang/e_rem_pio2.c
      2	libjava/java/lang/e_asin.c
      2	libjava/gnu/java/nio/natFileChannelImpl.cc
      2	libjava/gnu/gcj/runtime/natSharedLibLoader.cc
      2	libjava/gnu/gcj/io/shs.cc
      2	include/java-signal.h
      1	gcc/java/jvspec.c

Now, looking at the compile of the top two files, we see the
following:

Well, just FYI...
