rust-sdl2 fails to build on Windows

[RainbowCookie32]

I ran into this issue while trying to set up Github Actions with my project. The Linux build passes just fine, but for some reason, the same build on Windows fails. The offending lines seem to the on rwops.rs

rust-sdl2/src/sdl2/rwops.rs

Line 134 in f9e6c2a

((*self.raw).read.unwrap())(self.raw, buf.as_ptr() as *mut c_void, 1, out_len as u64)

rust-sdl2/src/sdl2/rwops.rs

Line 144 in f9e6c2a

((*self.raw).write.unwrap())(self.raw, buf.as_ptr() as *const c_void, 1, in_len as u64)

More specifically, the as u64 cast. The build output complains that both lines should be using as u32 instead, which does fix the build, but I'm not sure if it's the proper fix or if there's something else going on that I'm not aware of.

I attached both the normal and the verbose build logs below. My project builds using both bundled and static-link btw.

output_normal.log
output_verbose.log

For the time being, rev = "4e81db5" compiles on windows.

Yup, it does build. I'll leave the issue open until the regression is fixed then, I assume

My bad, in those two lines we need to replace as u64 into as sys::size_t and it should compile.
