You definitely /don't/ need a separate copy and /can/ use the IA32 Bochs
sources. It works fine. That's what I've been doing. Look at the
conf.COG files. They differ only in configure options. They build all
objects locally, taking only source from processors/IA32/bochs
oscogvm$ diff build.macos32x86/bochsx*/conf.COG
