+# rustc will remove one of the two redundant references to foo below.  Depending
+# on which one gets removed, we'll get a linker error on SOME platforms (like
+# Linux).  On these platforms, when a library is referenced, the linker will
+# only pull in the symbols needed _at that point in time_.  If a later library
+# depends on additional symbols from the library, they will not have been pulled
+# in, and you'll get undefined symbols errors.
+#
+# So in this example, we need to ensure that rustc keeps the _later_ reference
+# to foo, and not the former one.
