Sorry, David, but the 2.95 kernel is essentially offered "as is" at this point.
I had not planned on releasing any new versions.

However, that said, if you do find a fix for this problem I'll be willing to
apply it and respin gcc.  I just am not going to be tracking down the problem
myself.

Sorry, but I barely have the time these days for gcc 3.3.1.  2.95* is off the
radar entirely.
