definitevely 32 bits:
$ file  emacs-24.2.93/src/bootstrap-emacs
emacs-24.2.93/src/bootstrap-emacs: executable (RISC System/6000) or
object module not stripped

(if would have been "64-bit XCOFF executable or object module" if it was 64bits)

No problem with that version: downladed and compiled successfully

I never used IBM toolbox emacs, always compiled from source

I'm currently using:

GNU Emacs 24.2.1 (powerpc-ibm-aix5.3.0.0, X toolkit)
