-On the PE target, weak aliases are supported natively.  Weak aliases
-(usually called "weak externals" in PE) are created when an alternate
-name is specified.  When a weak symbol is linked and the symbol is not
-defined, the weak symbol becomes an alias for the alternate symbol.  If
-one equal sign is used, the linker searches for defined symbols within
-other objects and libraries.  This is the usual mode, historically
-called "lazy externals."  Otherwise, when two equal signs are used,
-the linker searches for defined symbols only within other objects.
