Re: Is 21.x going to be 64-bit clean?

Yes, XEmacs does compile as a 32-bit application just fine. As a 64-bit application, it compiles (after some electroshock therapy: 64-bit libaudio, compiling other support libraries for 64-bits, etc.) however it hangs at the following point of the make (this is a 20.4 example, but the same occurs with 21.x): EMACSLOADPATH="/public/Users/cfs/Build/xemacs-20.4/src/../lisp/prim" ./temacs -batch -l ../prim/update-elc.el Loading ../prim/update-elc.el... Loading /public/Users/cfs/Build/xemacs-20.4/src/../lisp/prim/dumped-lisp.el... temacs does not do any system calls, it just spins eating 100% of the CPU.
