The build should test x86, x64, nightly, and stable

[kennykerr]

Currently it only builds x64 and there may be x86 issues that go undetected. For example, these functions are only available for x64 builds:

windows-rs/examples/clock/src/main.rs

Lines 724 to 729 in bf5efbf

	#[link(name = "user32")]
	extern "system" {
	fn SetWindowLongPtrA(window: HWND, index: i32, value: isize) -> isize;
	fn GetWindowLongPtrA(window: HWND, index: i32) -> isize;
	}

We need to use GetWindowLongA and SetWindowLongA for x86 builds.

The build should perhaps also run nightly and stable, not just stable.

I've not yet been able to find the root cause of the issue in rustc, but it seems to be an issue from the renaming of the crate in the Cargo.toml file. If you change windows_gen Cargo.toml file to specify windows_gen_macros like so windows_gen_macros = { path = "macros", version = "0.4.0" } and rename all instances of macros to windows_gen_macros inside the windows_gen crate, the code compiles with cargo +nightly build --target=i686-pc-windows-msvc.

Of course, the issue in rustc should be fixed so it's up to you whether you want to implement the workaround or wait until the compiler is fixed.
