syntax error: token -> '/' ; column 1

I wrote "display.h" this way:

#ifndef __DISPLAY_H_
#define __DISPLAY_H_

const  unsigned int display_segment[10] ={
0x3f,
0x06,
0x5d,
0x4f,
0x65,
0xd5,
0x7d,
0x07,
0x7f,
0x4f
}

const unsigned int display_digit[0]={
0x01,
0x02,
0x03,
0x04,
0x05,
0x06,
0x07
}

void segmentDisplay(unsigned int segment){};
void digitDisplay(unsigned int digit){};
void numberDisplay(unsigned int* segment, unsigned int digit){};

__sfr __at(0x80) P0;
__sfr __at(0xA0) P2;
__sbit __at(0xA0+2) P2.2
__sbit __at(0xA0+3) P2.3
__sbit__at(0xA0+4) P2.4

#endif

and, "display.c" this way:

#define"display.h"

void segmentDisplay(unsigned int segment)
{
        P0 = display_segment[segment];
}

void digitDisplay(unsigned int digit)
{
    P2 = display_digit[digit];
}

void numberDisplay(unsigned int* segment, unsigned int digit)
{
    display_segment(*segment);
    display_digit(digit);
}

after "sdcc -c -mmcs51 --std-sdcc89 display.c", it prompted:

display.h:5: warning 190: ISO C forbids an empty source file
display.h:5: syntax error: token -> '/' ; column 1

what's wrong with it?

Problem solved by following changes:
1. add ";" at the end of array definition.
2. there should not be "{}" at the end of function declaration.
3. "P2.2" should be "P2_2".
4. "sdcc -c -mmcs51 --std-sdcc89 display.c" should be "sdcc -c -mmcs51 display.c".
