Re: [PATCH v3 0/2] Replace intl/ with out-of-tree GNU gettext

Don't build with the dependent libraries in tree.  Don't build the
dependent libraries as shared libraries. The libraries are already built
and in /opt/cfarm, as mentioned in the Compile Farm wiki.

AIX is not Solaris and not Linux.  It doesn't use ELF.  AIX shared
libraries *ARE* shared object files in archives.  Shared object versioning
is handled by multiple objects in the same archive.

Thanks, David
