Thanks for the explanation, Honza.
In that case, I guess leave it as is unless someone else wants to
see this changed.
As another note, "declaration merging" once occurs in our codebase,
in varpool.c:
/* When doing declaration merging we have duplicate
entries for given decl. Do not attempt to remove
the boides, or we will end up remiving
wrong one. */
Should this read "Do not attempt to address this, or we risk removing
the wrong one" or something like that?
