# 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.
