get rid of warnings ?

[Aurelien]

Hi,

I keep getting those noisy warnings:

/usr/local/bin/ld: warning: type and size of dynamic symbol 
'__objc_class_name_NSURL' are not defined
 or
Address.m:77: warning: '__objc_class_ref_NSObject' defined but not used

Does someone know how to get rid of them ?

Cheers,

Aurélien
