 I noticed this when trying to build libgcc on a Leopard VM:

 My hunch is that gcc's build system is checking sizeof(long) at configure
 time for x86_64 and using it for the i386 slice:

 {{{
 configure:5912: /usr/bin/gcc-4.2 -arch i386 -arch x86_64 -o conftest -g
 -L/opt/local/lib -Wl,-headerpad_max_install_names
 conftest.c  >&5
 configure:5912: $? = 0
 configure:5912: ./conftest
 configure:5912: $? = 0
 configure:5927: result: 8
 }}}

 This needs to be solved in a way similar to how we solve it in X11:

 verbatim.h
