Ok. I might use it in some other case. I needed version info as a global 
variable in several places for many functions and I can't set 
stand-alone if-statement inside a class.

This works outside class as a global variable even if it is not very smart

if(intval(substr($GLOBALS['TYPO_VERSION'],0,1)>3))
	$Typo4=1;

it doesn't matter, if some Typo3 version doesn't use that variable 
because the purpose is return true only if typo3 version is bigger than 3x
