This directive sets the weak attribute on the comma separated list of symbol names. If the symbols do not already exist, they will be created.
Weak symbols are supported in COFF as a GNU extension. This directive sets the weak attribute on the comma separated list of symbol names. If the symbols do not already exist, they will be created.

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.
Non-alias weak symbols are supported on PE as a GNU extension.
