Problem with echo ....

	Hi,
		We have shell scripts which works on Digital, SunOS and AIX machines. Recently we ported our scripts on Linux machine.
		On Linux machine echo is behaving differently because of this we are facing some problems.
		i.e
		echo "raghu\tkumar"
		raghu\tkumar
		Same command on SunOS giving "raghu   kumar" output.
		On Linux machine we need to use -e switch to expand backslash-escape characters which is not there in other machines.
		When  I modified echo.c source and  uncommented line no 53 (#define V9_DEFAULT), then it is working fine.
		Please confirm this modifications is correct or not.

	Regards,
	Raghu.
