include ../tools.mk # ignore-windows-msvc # 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.
