When I have my locale set to 'en' with setlocale(), the NumberFormatter class 
works just fine.

If I set the locale to, for example, 'fr_FR', the NumberFormatter class fails, 
giving a 'NaN' result. This is irrespective of the fact that the setlocale() 
function has clearly worked, as evidenced by gettext() working just fine.

I can't see any reason why the setlocale function should have anything to do with 
the operation of NumberFormatter: this isn't documented, and I'm explicitly 
passing the locale I want to use in the parameter.

Using 5.3.5 (the most recent available through MacPorts)

Test script:
---------------
setlocale(LC_ALL, 'en');
$nf = new NumberFormatter('de_DE',NumberFormatter::DECIMAL);
print $nf->format(123456.789);	// Outputs the correct answer 123.456,789 
print "<br/>\n";
setlocale(LC_ALL, 'fr_FR');	
$nf = new NumberFormatter('de_DE',NumberFormatter::DECIMAL);
print $nf->format(123456.789); // Outputs NaN

Expected result:
----------------
123456.789<br/>
123456.789

Actual result:
--------------
123456.789<br/>
NaN
