OS DEV C++

Ich benütze den DevCpp Compiler und er kann dass nicht compilieren

#include "system.h"

void *memcpy(void *dest, const void *src, size_t count)
{
    const char *sp = (const char *)src;
    char *dp = (char *)dest;
    for(; count != 0; count--) *dp++ = *sp++;
    return dest;
}

int *memset(void *dest, char val, size_t count)
{
    char *temp = (char *)dest;
    for( ; count != 0; count--) *temp++ = val;
    return dest;
}

unsigned short *memsetw(unsigned short *dest, unsigned short val, size_t count)
{
    unsigned short *temp = (unsigned short *)dest;
    for( ; count != 0; count--) *temp++ = val;
    return dest;
}

size_t strlen(const char *str)
{
    size_t retval;
    for(retval = 0; *str != '\0'; str++) retval++;
    return retval;
}

unsigned char inportb (unsigned short _port)
{
    unsigned char rv;
    __asm__ __volatile__ ("inb %1, %0" : "=a" (rv) : "dN" (_port));
    return rv;
}

void outportb (unsigned short _port, unsigned char _data)
{
    __asm__ __volatile__ ("outb %1, %0" : : "dN" (_port), "a" (_data));
}

int main()
{
    int i;

    gdt_install();
    idt_install();
    isrs_install();
    irq_install();
    init_video();
    timer_install();
    keyboard_install();

    __asm__ __volatile__ ("sti");

    puts("Willkommen im MF OS 1.0\n");

//    i = 10 / 0;
//    putch(i);

    for (;;);
}

und das ist die headerdatei
