13// This slightly odd translation unit exists because of the peculularity of how
14// allocator_unittests work on windows.  That target has to perform
15// tcmalloc-specific initialization on windows, but it cannot depend on base
16// otherwise. This target sits in the middle - base and allocator_unittests
17// can depend on it. This file can't depend on anything else in base, including
18// logging.
