GNU LD provides __ImageBase symbol since 2.19. This is standard windows symbol and should be used instead of custom gnu _image_base__ symbol.For compatibility with older GNU LD versions, define __ImageBase as weak alias to _image_base__ symbol. This allows to remove all #ifdef hacks for older GNU LD versions as with this change __ImageBase works correctly with all GNU LD versions. ---
Generally speaking, one shouldn't use weak symbols when targeting Windows. I haven't investigated though, but many times weak symbols result in null or faulty addresses.
Thus, weak symbols are unacceptable; but removal of references to `__image_base__` seems fine, if dropping support for binutils 2.18 is acceptable. BTW 2.19 was released in 2008 [1].
