I think the important question is whether older debuggers would be able
to deal gracefully with these location entries or constant values. I
understand they're supposed to, and I have no evidence that GDB isn't,
so I offer this patch to revert the last-minute addition of tests for
dwarf_version >= 4 in the VTA merge patch.
Should I check it in so that we can get a better idea of what, if
anything, breaks?
