Not quite. It will only get defined if it is not already *and*
INCOMING_RETURN_ADDR_RTX is defined. Code in final.c then checks whether
DWARF2_UNWIND_INFO is defined or not, it does not check its value. For an
a.out machine using stabs (eg netbsd/arm32), defining this to 0 or 1
causes dwarf information to be sucked into the build.
I think the tests on DWARF2_UNWIND_INFO should not be on whether or not it
is defined.
