It is only called when initializing  a function context key in unwind-sjlc.c
Maybe the best way to get rid of this whole problem would to use Dwarf2 unwind.
http://gcc.gnu.org/ml/gcc-patches/2004-11/msg01989.html
This would also faciltate use of jcr section to register java classes

I plan to submit an updated patch for Dwarf2 unwind on mingw after GCC branches.

Yes, that would be great - moving to Dwarf2 unwind on mingw would certainly solve a lot of problems for GCJ. Are you able to unwind through Windows system callback frames? I believe this was the major objection to Dwarf2 on mingw last time around.
