This version dies instantly for me.  Even emacs -nw dies.  Here is a 
backtrace, I can debug some more if that helps. I did:
./configure --prefix=/usr/local --verbose --with-x=no
make bootstrap

Program received signal EXC_BAD_ACCESS, Could not access memory.

Nevermind, I did everything from scratch again, and now it is OK.

Hi Everyone,

I have just checked in to the CVS a very nice patch contributed by
Steven Tamm which lets Emacs recognize 2- and 3-button and wheel mice.
Attached below is his description of it, among other things.

Also recently changed in the CVS is the creator code of the Emacs
application from ???? to EMAx.

Andrew.
