Re: 64-mode compile on AIX

[Bob Friesenhahn]

There was an earlier discussion on a libtool list regarding this 
issue.  The easiest workaround is to define the environment variable 
OBJECT_MODE (OBJECT_MODE=64) before running configure or building any 
code.  There is an ar option for supporting either type of object but 
older versions of the build tools do not support it so it is not 
reliable.
