Yes, that finally does the trick.

In my build dir:
config.log:
USE_LIBGCJ_BC_FALSE='#'
USE_LIBGCJ_BC_TRUE=''
config.status:
s,@USE_LIBGCJ_BC_TRUE@,,;t t
s,@USE_LIBGCJ_BC_FALSE@,#,;t t
4 Makefiles:
USE_LIBGCJ_BC_FALSE = #
USE_LIBGCJ_BC_TRUE =
Are these correct? In config.log for instance, I also see:
USING_BOEHMGC_FALSE = #
USING_BOEHMGC_TRUE =
Since I configure with "--enable-java-gc=boehm", I would assume that no
value means to set it. So USING_BOEHMGC_TRUE and USE_LIBGCJ_BC_TRUE
should be set.
BTW, in my host=Windows target=Linux GCC, I also have a libgcj_bc.a,
libgcj_bc.so.1 and libgcj_bc.so.1.0.0. These shouldn't have been built
either, right?

What about the the host=Linux target=Linux compiler? -findirect-dispatch
doesn't work either. So I end up with a wrong *lib line there too. And I
guess there I really have LIBGCJ_BC.

And what about my Linux one?
