Here's a patch with which I was able to build Emacs 23.4 on x32 under Debian. (I chose to make EMACS_INT 32-bit in the x32 spirit of reducing memory / cache usage.) Since I don't have access to add it to the X32 Patches page afaict, I'm posting it here.

Checking _ILP32 is more reliable than _LP64 since _LP64 isn't specified
by the x86-64 psABI.

OK, thanks, I'll keep that in mind for the future. (On the other hand, there was already a check for _LP64 in src/lisp.h...)
