D/Objective-C, extern (Objective-C)

[Jacob Carlborg]

As some of you might know Michel Fortin created a fork of DMD a couple 
of years ago which add support for using Objective-C classes and calling 
Objective-C method. That is making D ABI compatible with Objective-C.

I have now updated it to the latest version of DMD and druntime. All 
D/Objective-C tests pass and all standard tests pass. I'm planning to 
create a DIP for this and would really like this to be folded into main 
line. For know you can read the design document created by Michel:

Original project page: http://michelf.ca/projects/d-objc/

My forks:
DMD: https://github.com/jacob-carlborg/dmd/tree/d-objc
druntime: https://github.com/jacob-carlborg/druntime/tree/d-objc
Phobos: standard Phobos, commit f85bd54ef5615986960fdd68ea87c8aaf5c5118d

Currently I have limited bandwidth and cannot upload a pre-compiled 
binary. To compile use the following commands:

cd dmd/src
make -f posix.mak MODEL=32 D_OBJC=1

cd druntime
make -f posix.mak DMD=../dmd/src/dmd MODEL=32 D_OBJC=1

cd phobos
make -f posix.mak DMD=../dmd/src/dmd MODEL=32

Currently D/Objc only works for 32bit. You can use Michel's example 
application, Chocolate, to try it out. It's a bit cumbersome to compile 
without Xcode but it's possible.
