types are not respected with -no-builtin

[4zv4l]

Describe the bug

When compiling C project with -no-builtin, when using voidptr it does not translate to *void.
And when using variadic function, it creates a typedef array which does not exist

Reproduction Steps

helper.c

#include <linux/module.h>
#include <linux/proc_fs.h>

#define VV_LOCAL_SYMBOL
#define EMPTY_STRUCT_DECLARATION

MODULE_LICENSE("GPL");
MODULE_AUTHOR("4zv4l");

int kern__custom_init(void);
void kern__custom_exit(void);

module_init(kern__custom_init);
module_exit(kern__custom_exit);

proc.c.v

module kern

#include "helper.c"

fn C.pr_info(...charptr)
fn C.proc_create(charptr, int, int, &C.proc_ops)
fn C.remove_proc_entry(charptr, int)
struct C.proc_ops {
    proc_read fn(voidptr, &char, u32, &u64)
}

fn proc_read(file voidptr, buff &char, size u32, offset &u64) {

}

__global fops = C.proc_ops{proc_read: proc_read}
fn custom_init() int {
    C.pr_info(c"Hello module %s!\n", c"proc")
    C.proc_create(c"proc_proc", 0666, 0, &fops)
    return 0
}

fn custom_exit() {
    C.pr_info(c"Bye module !\n")
    C.remove_proc_entry(c"proc_proc", 0)
}

Makefile

obj-m += proc.o

all: proc.c
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
proc.c:
        vlang -no-builtin -no-preludes -enable-globals -gc none -o proc.c proc.c.v
clean:
        make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

Expected Behavior

translating voidptr into void*
and avoid creating a potential useless array typedef (when removed, it works without issue)

Current Behavior

doenst translate voidptr to void* and create a array typedef which make a compile error

Possible Solution

No response

Additional Information/Context

• line 48, the array definition
• 76, 96 the voidptr

V version

the global struct isn't initialized as it should as well
