Zurcher:
  https://www.nasm.us/xdoc/2.13.02rc3/html/nasmdoc7.html mentions wrt
..imagebase usage in 7.6 win64: Microsoft Win64 Object Files. 
  So, it is only for win64 object. VS and CLANGPDB tool chain uses nasm
win64 object. But, GCC5 uses nasm elf64 object, and XCODE uses nasm macho64
object.

  That means this native support for X64 is for VS tool chain only. 

Thanks
Liming
