The patches are not on the 3.0 branch yet for exactly this reason. ;-)

Thank you for contacting me directly (I am taking the liberty to CC
the list with this reply).  This is a known problem.  libjava doesn't
build with --enable-threads which is now the default for FreeBSD to
match our system compiler (I have seen more than a few bug reports
from people that misconfigured their FSF gcc to replace /usr/bin/gcc).

I suspect that you provided --enable-libgcj at configure time.  I have
an approved patch to allow libjava(libgcj) to build, but it is a
kludge that I am embarrassed to apply.

Would you like me to overcome my embarrassment and apply my approved
yet junky libjava patch or do you mind excluding that configure-time
option (or you can add --disable-threads to get back where you were
before the configuration patch).
