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.
