Well, it fixes something... at least now it breaks in another way (due to 
redefinition of BC it seems). 

More info:

I've tried to bootstrap from CVS (latest, 2002-11-01 and 2002-09-27) with
similar results:

make bootstrap fails with:
    ../src/bootstrap-emacs -batch --no-site-file --multibyte -l autoload 
    --eval '(setq generated-autoload-file "/Users/mk/emacs/lisp/loaddefs.el")' 
    -f batch-update-autoloads $wins

    /Users/mk/emacs/lisp/toolbar
    make[1]: *** [autoloads] Error 139
    make: *** [bootstrap] Error 2

closer examination (gdb) yields that bootstrap-emacs segfaults when 
initializing dyld:
    (gdb) run 
    Starting program: /Users/mk/emacs/src/bootstrap-emacs 
    [Switching to process 7017 thread 0xb03]

    (gdb) 

If I define DYLD_FORCE_FLAT_NAMESPACE it fails with:
    bash-2.05$ env DYLD_FORCE_FLAT_NAMESPACE= src/bootstrap-emacs 
    dyld: src/bootstrap-emacs multiple definitions of symbol _BC
    src/bootstrap-emacs definition of _BC
    /usr/lib/libncurses.5.dylib(lib_termcap.o) definition of _BC
    Trace/BPT trap
As you suspected.

I'm using 10.2.2 with latest developer tools (gcc 3.1).
