   Fact is, it should be using "makeC++SharedLib_r" in the first place,
which shouldn't need "-lC_r -lc_r" at all. If you don't have
makeC++SharedLib_r or you have an omniORB release which doesn't use it,
I'd be interested in hearing about it. 2.6.1 builds fine on AIX
4.2.1/xlC 3.1.4.7 with only a single change: modify
mk/platforms/powerpc_aix_4.2.mk to use "bsdinstall instead of "cp" and
build as root. Getting a GNU version of "cp" might get around the
problem as well.
   Also, if you are using "/usr/lpp/xlC/bin/makeC++SharedLib -lC -lc ..."
for libomniORB2 as well, that will cause your code to eventually break
too, since you will be combining thread-safe new/delete with the
non-thread-safe ones, eventually causing memory corruption. You'll see
it a lot faster on a multiprocessor box, but eventually on a
uniprocessor as well. Make the same change and you should be fine. To
check to see if it is right, try this:

% dump -H omniORB_2.6.1/lib/powerpc_aix_4.2/libomniORB26.a

   Note that there is no reference to "libC.a" or "libc.a", which is
how it should be, though it might be a bit different on other versions
of AIX.
