I see the same on the latest nightly, both with and without customizations:

In GNU Emacs 24.0.90.3 (i386-apple-darwin9.8.0, NS apple-appkit-949.54)
 of 2011-12-30 on braeburn.aquamacs.org - Aquamacs Distribution 3.xdev
Windowing system distributor `Apple', version 10.3.1038
configured using `configure  '--with-ns' '--without-x' 'CFLAGS=-arch
i386 -g -O0 ' 'LDFLAGS=-arch i386 -g -O0 ''

Whoops, I knew I was forgetting something. Here are the relevant extracts:

In GNU Emacs 23.3.50.1 (i386-apple-darwin9.8.0, NS apple-appkit-949.54)

Windowing system distributor `Apple', version 10.3.1038

'CFLAGS=-O0 -g -arch i386' 'LDFLAGS=-O0 -g -arch i386''
