Inconsistent C translated type among msvc and gnu abi?

test.h

enum CXCursorKind {
  CXCursor_UnexposedDecl = 1,
  CXCursor_StructDecl = 2,
};

main.zig:

const std = @import("std");
const c = @cImport({
    @cInclude("test.h");
});

pub fn main() !void {
    std.debug.print(
        "TypeName(c.CXCursorKind): {s}\n",
        .{@typeName(c.CXCursorKind)},
    );
}

zig build run results: TypeName(c.CXCursorKind): c_uint
zig build run -Dtarget=x86_64-windows-msvc results: TypeName(c.CXCursorKind): c_int

the variants all result in c_int type for both abis. so it’s kind of an issue if gnu abi sets the enum type(s) as c_uint, can’t directly pass the variants to the functions which accepts the enum without @intCast and it’s kinda annoying.

Not really a Zig issue. C’s underlying type of enums is implementation defined.
