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.

Richard.
