Hi Ralf,
i tried destilling your rev 163580 patches into one accumulated backport to
gcc-4.4.4. in our openembedded cross development toolchain. 
http://pastebin.com/pU3zF6MP

the patch actually does apply correctly, but during compile time, fails in the
libjava directory:
...
libtool: link: ( cd ".libs" && rm -f "libgcj_bc.la" && ln -s "../libgcj_bc.la"
"libgcj_bc.la" )
/bin/bash: GCC_FOR_ECJX@: command not found

turns out that the generated Makefile has the line GCC_FOR_ECJX =
@GCC_FOR_ECJX@ in it, so the variable wasn't substituted correctly during
configure, even though config.log says GCC_FOR_ECJX='x86_64-linux-gcc'

i probably need to backport other parts to be able to apply this patch
correctly on gcc release 4.4.4. but unfortunately the revision log
http://gcc.gnu.org/viewcvs/trunk/libjava/configure.ac?view=log&pathrev=163580
doesn't have information about the releases

is there an easy way to find out what else i need?

greetings,
fraxinas

It's hard to say.  I'd just import libgcj from gcc trunk.

Andrew.

dear dima, thanks for that patch but it's not sufficient. it even applies and
configures right but too many things had changed between release 4.4.4 and
revision 163580. so the resulting generated makefile is faulty and leaves the
variable @GCC_FOR_ECJX@ unsubtituted which causes compile to fail.
instead, i did it like Andrew proposed and simply imported the entire libjava
directory from svn head with which it works correctly.


now i am struggeling to cross compile statically linked mipsel java code with a
c++ .so linked to it...

This patch does apply against snapshot gcc-4.4 branch 26-09-2010. And does
build libgcj & java cross-compiler from i386|x86_64-gnu-linux to
i686-w64-mingw32.
After the patch is applied you do need to rerun correct autoreconf (2.59).

I believe libtool wasn't doing the right thing without any sources, but it has
been a while, so I don't remember the details.

Hmm, I seem to have approved that patch.
I agree with you: I can't see why the specfile change requires ecjx.cc.

I think it isn't correct to use "gcc" directly.
You probably have to introduce a new variable.

But, I don't see why we need ecjx.cc at all.
I think it must be to work around some other problem.
Maybe instead we could just fix that problem directly.

Apparently it came in here, though I don't see why:

This sounds correct to me . Adding one of the libjava maintainers to comment on
this. Patches should be submitted to the correct mailing list.
