Interfacing HC-SR04 Ultrasonic Sensor with PIC 16F676 using Hi-Tech C

With reference to the article Interfacing HC-SR04 Ultrasonic Distance Sensor with PIC Microcontroller, I am trying to change the microcontroller to PIC 16F676.

#define _XTAL_FREQ 8000000

#define RS RC5
#define EN RC4
#define D4 RC0
#define D5 RC1
#define D6 RC2
#define D7 RC3

#include <htc.h>

#include "lcd.h";
#include <pic16f676.h>

#pragma config WDTE = OFF // Watchdog Timer Enable bit (WDT enabled)
#pragma config PWRTE = OFF // Power-up Timer Enable bit (PWRT disabled)
#pragma config BOREN = ON // Brown-out Reset Enable bit (BOR enabled)
//#pragma config LVP = OFF // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)
#pragma config CPD = OFF // Data EEPROM Memory Code Protection bit (Data EEPROM code protection off)
//#pragma config WRT = OFF // Flash Program Memory Write Enable bits (Write protection off; all program memory may be written to by EECON control)
#pragma config CP = OFF // Flash Program Memory Code Protection bit (Code protection off)

I am using Hi-Tech C compiler and getting following errors.

Error [1347] ; 0. can’t find 0x21 words (0x21 withtotal) for psect “text142” in segment “CODE” (largest unused contiguous range 0x1E)
