Since strlcpy returns a size_t, you can make this a size_t now, and get rid of
the cast in the DCHECK.

I would have preferred a ScopedCFTypeRef<CFDataRef> to ward off the possibility
of future early returns. That would be the style of this file, I don’t see
CFRelease called directly anywhere else.

This doesn’t cause a compilation failure? I think that the internal
implementation of COMPILE_ASSERT is such that array_sizes_must_match will show
up as a variable, and this will look like you’re redeclaring a variable at the
same scope as a previous declaration. Compiler error! Line 249 too.

[Scott Byer, 2012/01/20 23:59:35]

No, it didn't, weird, huh? Looking at the macro, I'm surprised, too. Fixed up
this one just for paranoia - 249 is OK, since 183 is in a scope.
