Help me fix a software UART routine for PIC18F452

[saeed_pk]

I am about to use a software UART Routine on PIC18F452
This Routing is working well for PIC16F877A I am using PICC and PICC-18 Compiler for this purpose please
review the sourece code

#include <pic.h>
#ifndef RS232_H
#define RS232_H

//Defines

#define	CLEAR		0
#define	SET			1

//Modify these parameters for your device
//Main I/O
#define	RX			RC5
#define	TX			RC4
#define	RX_ASM		_PORTC,5
#define	TX_ASM		_PORTC,4
#define	TRIS_TX		TRISC4
#define	TRIS_RX		TRISC5


//Global Variable Declarations
unsigned char delayconstant,txreg,bitcount,rxreg,baudrate; 

//Function Prototypes
#endif

Function Definition file rs232.c is as under (I require inly serial reception)

#include "rs232.h"


unsigned char Receive()
{
	TRIS_RX = SET;
	
	delayconstant = baudrate;
	bitcount = 9;
	
	#asm
		
		btfsc	RX_ASM
		goto	$-1
		decfsz	_delayconstant,f
		goto	$-1
		movf	_baudrate,w
		movwf	_delayconstant
		decfsz	_bitcount,f
		goto	$+2
		goto	$+6
		bcf		_STATUS,0
		btfsc	RX_ASM
		bsf		_STATUS,0
		rrf		_rxreg,f
		goto	$-11
	#endasm

	return rxreg;
}

when i call this function in main function for PIC18F452 then it gives following errors

Error[000] C:\Documents and Settings\Administrator.EWI-ATACTS\Desktop\SOFT-ASm\rs232.obj 15 : Fixup overflow referencing psect bigbss (loc 0x118 (0x10A+14), size 1, value 0x5E7)

Error[000] rs232.rlf 43 : Fixup overflow in expression (loc 0x5EC (0x5EC+0), size 1, value 0x5E8)

please help me updating this function for PIC18F452 of Convert the assembly portion in C
