Hi Tim,

> ld/configure.host:  Add ia64-*-aix* configuration.
> ld/configure.tgt: Ditto.
> ld/emulparams/elf64_aix.sh: New.  Settings for AIX output files.
> ld/testsuite/ld-bootstrap/bootstrap.exp: Exclude AIX/IA-64 from usual

Approved.

BTW - do you have write access to the CVS repository, or do you need
these patches checked in for you ?

Cheers
