Jeremy, thanks for the reply. Very good to hear that the build completed.

I'll start an optimized build tonight. If it comes down to it, a patch
could be created to not pass OTHER_CXXFLAGS to the jar/jarutils subdirs.
Unfortunately, my equip is a little older, -march=athlon will have to
do for my testing, though we'll probably find the culprit to be -O3. :-)

Robert, I wasn't sure if you followed this list or not, sorry in advance
for the CC if so. Did you by chance use optimizations in your build
that failed with the same error?
Thanks.
