20e5aa35e5 Added GSBlocks header. This defines two macros: 
DEFINE_BLOCK_TYPE() defines a new block type.
CALL_BLOCK() calls a block.

These use the compiler's native support for blocks if it exists, but otherwise implement the lower-level version.  Note that the structure defined by the fall-back versions is NOT a complete definition of the block layout, and copies of this structure should never be instantiated.

This does not allow non-blocks-aware compiles (like GCC) to create blocks, but it does allow them to use blocks.  This means that we can implement things like NSArray's -enumerateObjectsUsingBlock: without breaking GCC compatibility.  To do so, you'd first need to declare a block type in the header, like this:

DEFINE_BLOCK_TYPE(GSEnumeratorBlock, void, id, NSUInteger, BOOL*);

Then declare the method like this:

- (void)enumerateObjectsUsingBlock: (GSEnumeratorBlock)aBlock;

Finally, implement it like this:

- (void)enumerateObjectsUsingBlock: (GSEnumeratorBlock)aBlock
{
	NSUInteger count = 0;
	BOOL shouldStop = NO;
	for (obj in self)
	{
		CALL_BLOCK(aBlock, obj, count++, &shouldStop);
		if (shouldStop)
		{
			return;
		}
	}
}

If you compile this with clang -fblocks then it will work using Clang's native support for blocks.  If you compile it with GCC or clang without -fblocks then it will use the other version.  Note that this example uses fast enumeration, so will only compile with clang.  A proper GNUstep implementation should have some fall-back code for primitive compilers that don't support this either.

fffe50ffdc Added call to objc_create_block_classes_as_subclasses_of() in NSObject's +load method. This is called as soon as NSObject is loaded and creates the _NSBlock family of classes, which are statically allocated in the runtime but not statically initialised. If you create blocks without linking GNUstep-base, the isa pointer in the block will point to a class that has all of its fields set to 0. 
Any blocks will have their isa pointer set to the two classes statically allocated in libobjc, but these classes can't be used for message lookup (or introspection) until after the call.  This means that you can't send messages to blocks until after NSObject's +load method has been called.  This shouldn't be a problem in most code, but if you use __attribute__((constructor)) instead of a +load method then be careful about sending messages to blocks (you can still call them as normal).
