Not much success,

1st try using default gcc options, it fails like this:

cd /sg/paxdev5/D1stunix/src/emacs/24.2.93/emacs-24.2.93/lisp && chmod
+w ps-print.el emulation/tpu-edt.el emacs-lisp/cl-loaddefs.el
mail/rmail.el dired.el ibuffer.el htmlfontify.el emacs-lisp/eieio.el
cd /sg/paxdev5/D1stunix/src/emacs/24.2.93/emacs-24.2.93/lisp;
subdirs=`find . -type d -print`; for file in $subdirs; do case $file
in */.* | */.*/* | */=* | */obsolete | */term ) ;; *) wins="$wins
$file" ;; esac; done; \
echo Directories: $wins; \

I then have tried to force 64 bit mode, with gcc and with xlc, none worked,

Here's what I get using xlc (CFLAGS="-q64", OBJECT_MODE=64)
unexec: couldn't find "|<" section
gmake[1]: *** [bootstrap-emacs] Error 1
gmake[1]: Leaving directory
`/sg/paxdev5/D1stunix/src/emacs/24.2.93/emacs-24.2.93/src'
gmake: *** [src] Error 2

(and be assured that I don't forget to do a "make distclean,
configure" between each tests)
