Bryce Denney 0a7cb3a43c - apply patch.ifdef-disabled-options. Comments from that patch are below: 
For a whole lot of configure options, I put #if...#endif around code that
  is specific to the option, even in files which are normally only compiled
  when the option is on.  This allows me to create a MS Visual C++ 6.0
  workspace that supports many of these options.  The workspace will basically
  compile every file all the time, but the code for disabled options will
  be commented out by the #if...#endif.

  This may one day lead to simplification of the Makefiles and configure
  scripts, but for the moment I'm leaving Makefiles and configure scripts
  alone.

  Affected options:
    BX_SUPPORT_APIC (cpu/apic.cc)
    BX_SUPPORT_X86_64 (cpu/*64.cc)
    BX_DEBUGGER (debug/*)
    BX_DISASM (disasm/*)
    BX_WITH_nameofgui (gui/*)
    BX_SUPPORT_CDROM (iodev/cdrom.cc)
    BX_NE2K_SUPPORT (iodev/eth*.cc, iodev/ne2k.cc)
    BX_SUPPORT_APIC (iodev/ioapic.cc)
    BX_IODEBUG_SUPPORT (iodev/iodebug.cc)
    BX_PCI_SUPPORT (iodev/pci*.cc)
    BX_SUPPORT_SB16 (iodev/sb*.cc)
