Is this base compilation warning a real problem?

[Fred Kiefer]

Compiling file NSDistributedNotificationCenter.m ...
NSDistributedNotificationCenter.m: In function
‘-[NSDistributedNotificationCenter
addObserver:selector:name:object:suspensionBehavior:]’:
NSDistributedNotificationCenter.m:343: warning: cast from pointer to

I am on a 32 bit intel machine, I expect 64 bit machines would handle
this code without warnings.
