Linux 64bit branch

[Jesse Phillips]

I wanted to mention that I have a branch for the base and gtk 
repositories which compile under 64bit.

https://github.com/JesseKPhillips/base/tree/64bit
https://github.com/JesseKPhillips/org.eclipse.swt.gtk.linux.x86/tree/64bit

I don't know if changes are correct, in the since that I don't 
have a grasp on the boundaries with the gtk libraries. They 
shouldn't affect 32bit though (it also compiles)

As I have not built a working example yet I won't be creating a 
pull request, the compiler message for snippet 107:

-------
(org-eclipse-swt-program-Program.o): undefined reference to 
symbol 'gnome_vfs_init'
//usr/lib/x86_64-linux-gnu/libgnomevfs-2.so.0: error adding 
symbols: DSO missing from command line
-------

Which could be an issue with ordering[1] or missing a library. I 
don't know if I'll get anything working, but wanted to provide 
information that there is a compiling lib for 64bit out there.
