Whilst I have a sometimes love hat relationship with picl I think it is
the right place for "platform" as it always references libraries from
/platform/`uname -i`. The problem may be that i86pc or x64 is probably
too generice for picld use. I think it would need to get much more
specific.
syshwd certainly sounds interesting. What drives those alerts?
