Paul,

'xlc -O' worked! emacs 24.3 has compiled and linked for me.

I would never have been able to read that diagnostic that way.

And thanks to all the developers who helped along the way!

If the majority of cooking accidents happen in the kitchen, then why don't we 
just cook in other rooms?

Erik's right that Emacs won't build properly when compiled
with a C++ compiler.  So vanilla xlc should be the way to go.

If plain xlc doesn't work, how about 'xlc -O'?  The remarks
in alloc.c's SETJMP_WILL_NOT_WORK indicate that you may need
to compile Emacs with optimization enabled, to get setjmp to
save registers properly.
