Properties with the __weak attribute should not have assign attribute

[GoogleCodeExporter]

Latest versions of LLVM indicate that the __weak property is not compatible 
with 'assign' on a property. The assign attribute needs to be removed.

I just ran into this as well.  Now that LLVM 3.0 is the default compiler, this 
has become an important issue!

I've fixed this within the latest repository push by creating a build-time 
defined term cpt_weak_property which translates to "weak" on projects that 
target iOS 5.0 and Lion, and "assign" on those deployed to iOS 4.0 and Snow 
Leopard.  To pair with this, __weak has been replaced with __cpt_weak, which 
falls back to __unsafe_unretained on the older deployment targets.

This should make the framework fully ARC-compatible now.

Actually putting this stuff to header files is lame.
Move your private instance variables, properties and methods to anonymous 
interface in .m files and compile them with whatever is able to digest it.
Header files should contain only public interface which is independent of those 
arc issues.

I agree it's ugly. If you've got a suggestion on how to clean this up, let's 
take the conversation to the discussion board ( 
http://groups.google.com/group/coreplot-discuss ). Private methods and 
properties are not the problem--these are already defined in class extensions 
in the .m files. Core Plot does not use synthesized instance variables because 
of the need to support 32-bit Mac apps. 

Keep in mind that as a library intended to be used in a wide variety of 
applications, it has to support all of the following environments:

* Execute on iOS 3.1.3+ and MacOS X (i86 and x86_64) 10.5+
* Compile on latest versions of Xcode under both MacOS X 10.6 and 10.7.
* Headers must be compatible with all compilers provided with Xcode.
* Headers must be useable in applications with and without ARC.
