R help - Aug 2004 - readline, 64bit solaris build

I've built a 64bit version of R 1.9.1 on a solaris 2.9 sparc system.  
Everything
seems quite functional, except that readline produces the following:

in config.log...  do I interpret this correctly  as a gentle suggestion 
that
readline should be remade as a 64bit library?  Can this be done?  My
(superficial)  look at the readline docs didn't offer any advice in this
direction, nor did my googling produce any.

I realize that the real hidden message here is probably to accept
that it is time to make the transition to ESS, but I'm still resisting 
this,
and hope that someone could suggest a way to get readline going.

Yes, yes.  You need to build it with cc -xarch=v9 or gcc -m64: looks like 
I used the latter and probably there was a good reason.

Um, you need a 64-bit emacs with readline for a 64-bit ESS ....
