The following C header doesn't work with @cImport:
typedef enum {
f32,
u32,
} BadEnum;Here's a zig file to demonstrate:
const c = @cImport({
@cInclude("badenum.h");
});
pub fn main() void {
var a : c.BadEnum = undefined;
}$ zig build-exe badenum.zig -I.

var a : c.BadEnum = undefined;Modifying the enum identifiers to non zigkeywords fixes the issue. Zig's translate-c needs to be aware whether or not a C identifier is a keyword and handle it accordingly.
