PIC18f4550 / LCD16x2 / MIKRO C

Tengo una pregunta simple que me detiene.

Este programa ejecuta un error, aumenta "x" y muestra el resultado en la pantalla, pero ...

// LCD module connections
sbit LCD_RS at RD4_bit;
sbit LCD_EN at RD5_bit;
sbit LCD_D4 at RD0_bit;
sbit LCD_D5 at RD1_bit;
sbit LCD_D6 at RD2_bit;
sbit LCD_D7 at RD3_bit;

sbit LCD_RS_Direction at TRISD4_bit;
sbit LCD_EN_Direction at TRISD5_bit;
sbit LCD_D4_Direction at TRISD0_bit;
sbit LCD_D5_Direction at TRISD1_bit;
sbit LCD_D6_Direction at TRISD2_bit;
sbit LCD_D7_Direction at TRISD3_bit;

void main(){
 int x = 0;
 char txt[255];
 Lcd_Init();
 Lcd_Cmd(_LCD_CURSOR_OFF);
 Lcd_Out(1, 1, "Total:");
 Lcd_Out(2, 1, "$");

while(1){
     IntToStr(x, txt);
     Lcd_Out(2, 11, txt);
     x++;
     Delay_ms(100);
 }
}

Cuando agrego el código de configuración para tener 4 entradas en PORTA:

// LCD module connections
sbit LCD_RS at RD4_bit;
sbit LCD_EN at RD5_bit;
sbit LCD_D4 at RD0_bit;
sbit LCD_D5 at RD1_bit;
sbit LCD_D6 at RD2_bit;
sbit LCD_D7 at RD3_bit;

sbit LCD_RS_Direction at TRISD4_bit;
sbit LCD_EN_Direction at TRISD5_bit;
sbit LCD_D4_Direction at TRISD0_bit;
sbit LCD_D5_Direction at TRISD1_bit;
sbit LCD_D6_Direction at TRISD2_bit;
sbit LCD_D7_Direction at TRISD3_bit;

void main(){
 TRISA = 0B00001111;
 CMCON = 0B00000111;
 ADCON1 = 0X0F;
 PORTA = 0;
 int x = 0;
 char txt[255];
 Lcd_Init();
 Lcd_Cmd(_LCD_CURSOR_OFF);
 Lcd_Out(1, 1, "Total:");
 Lcd_Out(2, 1, "$");

while(1){
     IntToStr(x, txt);
     Lcd_Out(2, 11, txt);
     x++;
     Delay_ms(100);
 }
}

aparece el siguiente error:

Expresión no válida en la línea "int x = 0;"

Por favor, ayuda!
