Support Windows

[dubcanada]

http://win32builder.gnome.org/ has unoffical builds for 3.10 for Windows. Also this is another reason to have #1 to allow Windows people to use 3.6.4 (the last "official" release).

Either way it would be nice to redo the Makefile (or switch to something slightly more cross platform like cmake) to allow for Windows support.

We started to handle multiple versions (3.6, 3.8, 3.10 and 3.12). With this, it should be fine for Windows people to use it.
For the Makefile, we already were speaking about using cmake because it's more pleasant to use. I think it'll be added in a near future.

Window's dies while running rgtk-build at the moment. Access violation error for one of the pointers. Glue builds and appears to work fine.

@jeremyletang and myself aren't developing under windows. We'll test more on this platform when the development will be in a more advanced stage I think. Feel free to create a pull request if you fix that issue and thank you for your interest.

I played around with this a bunch, I just can't get past the rust compilation error. I am not sure if it is a Rust compiler error as there are a bunch of them on Windows. Or it is related to something else.

I reported it anyways rust-lang/rust#15811

The ICE on rust-lang/rust#15811 is triggered by src/gtk/signals.rs#L239:

signal!(show_help, ShowHelp(help_type : gtk::WidgetHelpType) -> bool)

which defines pub extern fn trampoline(widget: *mut ffi::C_GtkWidget, help_type: gtk::WidgetHelpType, ...) where struct WidgetHelpType; is empty.
Is it intended? It seems like *mut WidgetHelpType is appropriate but I don't know details.

[jeremyletang]

@klutzy thanks for the help !

It seems that WidgetHelpType was an enum, if change this in my last commit, maybe this fix the ICE?
Anyone on Windows can try ?

[dubcanada]

I'll give it a try later today.

(rust-lang/rust#16484 fixed the ICE issue!)
The remaining issue is that some codes assume pointer is 64-bit. (this seems relevant for 32-bit linux as well?)

After touching some lines, I've succeeded to get librgtk.rlib. So the "build" issue is nearly done!

Oh nice ! I like when bugs nearly disappear by themselves haha. Thanks !
