gcj adds a java resource named ".dummy" to most (all?) the object file it
produces. That resource doesn't appear anywhere in the sources.
This is a problem when I try to link an application made from multiple .o
produced by separate gcj invocations: I get the link-time error:
multiple definition of `java resource .dummy'
Also this is a regression as gcj 4.2.2 didn't add it and thus the linker didn't
complain.
gcc was built with the following options:
../gcc-4.4.3/configure --prefix="/opt/focuseek-build-fsk" \
--program-suffix=-fsk \
--enable-languages=c,c++,java \
--enable-shared --enable-threads \
--enable-__cxa_atexit \
--enable-libgcj-multifile
on a centos 5.4. The md5 for ecj.jar is d7cd6a27c8801e66cbaa964a039ecfdb which,
as of today, is what contrib/download_ecj retrieves.
I'm aware of bug 42143 but I'm not able to say whether this is the same bug or
another one.
I will attach a test case as soon as possible.

Experimenting with -save-temps I noticed that the .dummy resource is in the
.jar generated by ecj which seems to point to it as the main suspect.

If it comes from ecj, it's not a gcc bug.
