I can't reproduce this, works fine for me:

[derick@kossu derick]$ php
<?php
$foo = "";

if (isset($foo)) {
	echo "IN HERE!\n";
}
?>
IN HERE!
[derick@kossu derick]$ php -v

On 4.2.2 I've 

if(isset($namevar)){
//some statements
// It comes here if $namevar is set, even if $namevar="";
}

On 4.3.0-pre2 I've 

if(isset($namevar)){
//some statements
// It doesn't come if $namevar="";
}

You can't change that to much legacy....
