I will have to fix the linkage.

Do we need to link windowed bootloaders only with Carbon framework or with any other?
- in the 'wscript' there are the following lines and I'm not sure why:

  conf.env.append_value('LINKFLAGS', '-framework')
  conf.env.append_value('LINKFLAGS', 'ApplicationServices')

To compile 64-bit bootloader you need to run waf with 64bit python.
