I only just caught this (having seen the fallout from NetBSD doing the same thing in a shipping release and the pain that it’s caused):
__weak is a reserved keyword in Objective-C, please pick another name for this. This in cdefs.h makes it impossible to include any FreeBSD standard headers in Objective-C programs (of which we have a couple of hundred in ports) if they use any of the modern Objective-C language modes.
