Yes, if you mean this being the goal :

C:\opt\cross\bin>i686-mingw32-gcj-4.6 -v
Reading specs from c:/opt/cross/bin/../lib/gcc/i686-mingw32/4.6.2/specs
Reading specs from libgcj.spec
i686-mingw32-gcj-4.6: error: libgcj.spec: No such file or directory

Producing libgcj from the gcc-4.6.[23] sources doesn't currently work,
the (1st) error comes from compiling 'jni.cc' so basically the problem
is some C++ related problem. But my C++ skills are rusty so although
the problem might be simple :

-DLIBGCJ_DEFAULT_DATABASE_PATH_TAIL=\"gcj-4.6.2-12/classmap.db\" -g -Os 
-MT jni.lo -MD -MP -MF .deps/jni.Tpo -c ../../../libjava/jni.cc 
-DDLL_EXPORT -DPIC -o .libs/jni.o

../../../libjava/java/lang/reflect/Field.h:85:8: error: 'jint

../../../libjava/jni.cc:1670:14: error: within this context

it isn't so simple to fix without refreshing my C++ memory...

Maybe your question is: "is there anyone out there who has succeeded in
building gcc-4.6.x with gcj for MinGW-host/target on MinGW-build 
platform?"  As seen a partial answer for "is there anyone out there who
has succeeded in building gcc-4.6.x with gcj for MinGW-host/target?" is
"yes"... (It will succeed without the 'libgcj' library, requiring
'--enable-libgcj' in GCC configure)
