 // The main library imports lib1 and lib2 deferred and use lib1.foo1 and
 // lib2.foo2.  This should trigger seperate outputunits for main, lib1 and lib2.
 //
 // Both lib1 and lib2 import lib3 directly and
 // both use lib3.foo3.  Therefore a shared output unit for lib1 and lib2 should
 // be created.
 //
 // lib1 and lib2 also import lib4 deferred, but lib1 uses lib4.bar1 and lib2
 // uses lib4.bar2.  So two output units should be created for lib4, one for each
 // import.
