I don't think anyone has ever built CMake with that compiler before.
The only testing we have on AIX is with VisualAge 9.0.  See here:

   http://www.cdash.org/CDash/index.php?project=CMake

for tested platforms.  A new platform can become officially
supported if someone helps us get it working initially and also
starts submitting a nightly build to the dashboard.

This is not actually a configure check.  The "configure" script is
just an alias for the "bootstrap" script.  It's actually building
a minimal CMake which will generate a build system for all of CMake.

This is our own auto_ptr implementation which is needed to work around
lack of proper auto_ptr support on some compilers.  The implementation
defaults to standard C++ for unrecognized compilers.  However, this
old VisualAge compiler does not appear to be conformant enough to
support it.  We'll have to teach the implementation how to deal with
this compiler.

Please send me (off-list) the preprocessed output of the file being
compiled when this error occurs.
