I *added* the line (not replace) as you suggested, and now it generates a
new error during build:

c:/avrdev/gcc/gcc-4.3-20070914/libobjc/Object.m:66: error: unrecognizable
insn:
(insn 54 4 55 2 c:/avrdev/gcc/gcc-4.3-20070914/libobjc/Object.m:65 (set
(reg:QI 22 r22 [ D.2345 ])
        (subreg:QI (const:HI (plus:HI (symbol_ref:HI
("_OBJC_SELECTOR_TABLE") [flags 0x2] <var_decl 013C4A20
_OBJC_SELECTOR_TABLE>)
                    (const_int 8 [0x8]))) 0)) -1 (nil))
