gcj mingw32 and java memory footprint.

I haven't had a chance to try the patch.  But I would like to see something like this in, so long as there is a way to revert to current behavior, e.g. by setting an environment variable.

(It would be even better if we could get the new behavior starting at address A, and the old behavior for addresses below A, for a runtime specified A.  This would allow easy diagnosis of missing root registrations.  This shouldn't be too hard.)

Are you talking about http://gcc.gnu.org/ml/java/2002-06/msg00252.html?

I'd still be interested in seeing something like this for gcj, but got
zero feedback from the list the last time I mentioned it.
