Generated C headers contain includes that aren't needed

[gdoenlen]

Hi I'm compiling to freestanding and my generated C headers end up including things from std.

I only export the void main function and the other imports never import anything from the standard.
compile flags:

zig build-obj zworld.zig -target i386-freestanding-elfv1 -fno-PIC -I .

zig file:

const c = @cImport({
    @cInclude("types.h");
    @cInclude("user.h");
});

export fn main() void {
    c.printf(2, "hello world");
    c.exit();
}

generated header:

#ifndef ZWORLD_H
#define ZWORLD_H

#include <stdbool.h>

#ifdef __cplusplus
extern "C" {
#endif

void main(void);

#ifdef __cplusplus
} // extern "C"
#endif


#endif // ZWORLD_H

This is a bug, but both stdint.h and stdbool.h are present in even freestanding C implementations.

Hmm ok I guess you need stdbool and int for compatibility with zig primitives? Makes sense thanks!
