libgcj and MinGW, compilation problem

["Mathieu Velten" <matmaul at gmail dot com>]

Hello !
I crosspost here because of a recommendation on the gcc-help mailing
list, sorry for the double post.

I am trying to make a build of GCC 4.2.2 with GCJ for MinGW.

I first tried with :
../gcc-4.2.2/configure --enable-languages=c,c++,java -v
--enable-optimize --prefix=/mingw --oldincludedir=/mingw/include
--enable-threads --disable-nls --disable-win32-registry
--disable-shared --without-x

it compiled without any problem but when I try to launch gcj it
complains about the lack of libgcj, and effectivly libgcj is not
present. No problems with gcc or g++.

so I tried to add --enable-libgcj
and then I now have problems at the compilation time. the errors begin
like that :

and finish like that :

I tried to add also --enable-libjava but I have the same errors.

my build environment :
w32api-3.10.tar.gz
binutils-2.17.50-20060824-1.tar.gz
mingw32-make-3.81-2.tar.gz
mingw-runtime-3.13.tar.gz
pthreads-2.8.0
bison-2.1.0
gcc-4.2.2

Any suggestions to solve this problem ?

Thanks in advance for your answers.

Kind regards,
