Using mouse button mask (SDL_BUTTON_LMASK, etc.) leads to compile error

Minimal example:

const sdl = @import("sdl2");

pub fn main() void {
    _ = sdl.SDL_BUTTON_LMASK;
}

The error:

./deps/sdl/src/binding/sdl.zig:2475:32: error: expected type 'u5', found 'c_int'
    return @as(c_int, 1) << (X - @as(c_int, 1));
                               ^

Tested with zig-0.9.1 and zig-0.10.0-dev.1838+3bfb1616d.

The problem is within SDL_BUTTON() function:
https://github.com/MasterQ32/SDL.zig/blob/bf72bbef8c1c113b2862ff2fab33b1fedbf159f6/src/binding/sdl.zig#L2474-L2476

Experimented with intCast: return @as(c_int, 1) << @intCast(u5, (X - @as(c_int, 1)));
It fixes this issue, but I'm not experienced enough to know if this is the correct solution.

Making X comptime also fixes the error:
pub inline fn SDL_BUTTON(comptime X: c_int) c_int {
