Deavid,
this is patch to disable the vtable rewriting on AIX. I did not make much
progress
on figuring out why it fails today - just observed that if I produce .o file
for the
test and link it against libstdc++ built by older GCC it works. Also objects
compiled
w/o optimization works, so I am bit puzzled here.
