 That sounds like a good idea to me as well.

 My suggestion is that we define /usr/local/lib32 as a standard
 directory (and wire it into ld-elf32.so.1 in the same wap as /lib &
 /usr/lib) and extend /etc/libmap32.conf to define directory name
 mappings as well as dynamic object mappings to handle cases where
 LOCALBASE is not /usr/local and non-standard library directories.

 I would disagree on this point.  There's no reason why we need a working
 "cc -m32" in order to pkg_add an i386 package on an amd64 system.  I
 notice there was some discussion regarding multi-arch ports on -current
 in late March.

 Agreed.
