For a simple example it does not do this:
opsy. gcj -O2 -fPIC -fjni -findirect-dispatch -o H --main=HelloWorld
HelloWorld.class
opsy. eu-readelf -d H|fgrep lib
NEEDED Shared library: [libgcc_s.so.1]
NEEDED Shared library: [libgcj_bc.so.1]
NEEDED Shared library: [libm.so.6]
NEEDED Shared library: [libpthread.so.0]
NEEDED Shared library: [librt.so.1]
NEEDED Shared library: [libdl.so.2]
NEEDED Shared library: [libc.so.6]
I wonder if something else is going on here... maybe some optimization
is generating a symbol that necessitates pulling in libgcj itself?
(I'm thinking of the builtins ... though I thought Andrew fixed these.
So, maybe that is wrong.)

Bryce pointed out that we need to deal with the primitive class
objects somehow. Otherwise code like 'new int[5]' will pull in
libgcj.so.
I'll send a patch to the java-patches list.
Could you try it on your test cases?
I tried in on my copy of ecj.jar and verified that it works.

What does "ldd" on the dummy (unversioned) libgcj_bc.so say? This library
should not be linked against libgcj.so, maybe it is being linked incorrectly.

------- Comment #6 from debian-gcc at lists dot debian dot org 2006-08-23 09:20 -------
There seems to be a mismatch in the installation of the unversioned
libgcj_bc.so in the fc rpm and the trunk. On the trunk, this library is created
using
$(libgcj_bc_dummy_LINK) -xc /dev/null -Wl,-soname,libgcj_bc.so.1 \
-o $(DESTDIR)$(toolexeclibdir)/libgcj_bc.so.1.0.0 -lgcj
where libgcj is the real libgcj.so, while in the spec file, a dummy libgcj.so
is created first.
mkdir libgcj_bc
gcc/xgcc -B gcc/ $OPT_FLAGS $LIBGCJ_BC_CFLAGS -shared -fpic -xc /dev/null \
-o libgcj_bc/libgcj.so -Wl,-soname,libgcj.so.7rh -nostdlib
gcc/xgcc -B gcc/ $OPT_FLAGS $LIBGCJ_BC_CFLAGS -shared -fpic
../libjava/libgcj_bc.c \
-o libgcj_bc/libgcj_bc.so -Wl,-soname,libgcj_bc.so.1 libgcj_bc/libgcj.so
-shared-libgcc
Although that code seems to be called for the biarch case only.
The ldd on libgcj.so shows the dependency on the real libgcj on the trunk, no
dependency with the code from the spec file.

There's some kind of skew here... I took the code on the trunk
from the RH 4.1 branch, not from the FC RPM.
