-/*******************************************************
-
-Entry points used by the compiler - the real API!
-
-
-A Block can reference four different kinds of things that require help when the Block is copied to the heap.
-1) C++ stack based objects
-2) References to Objective-C objects
-3) Other Blocks
-4) __block variables
-
-In these cases helper functions are synthesized by the compiler for use in Block_copy and Block_release, called the copy and dispose helpers.  The copy helper emits a call to the C++ const copy constructor for C++ stack based objects and for the rest calls into the runtime support function _Block_object_assign.  The dispose helper has a call to the C++ destructor for case 1 and a call into _Block_object_dispose for the rest.
-
-The flags parameter of _Block_object_assign and _Block_object_dispose is set to
-	* BLOCK_FIELD_IS_OBJECT (3), for the case of an Objective-C Object,
-	* BLOCK_FIELD_IS_BLOCK (7), for the case of another Block, and
-	* BLOCK_FIELD_IS_BYREF (8), for the case of a __block variable.
-If the __block variable is marked weak the compiler also or's in BLOCK_FIELD_IS_WEAK (16).
-
-So the Block copy/dispose helpers should only ever generate the four flag values of 3, 7, 8, and 24.
-
-When  a __block variable is either a C++ object, an Objective-C object, or another Block then the compiler also generates copy/dispose helper functions.  Similarly to the Block copy helper, the "__block" copy helper (formerly and still a.k.a. "byref" copy helper) will do a C++ copy constructor (not a const one though!) and the dispose helper will do the destructor.  And similarly the helpers will call into the same two support functions with the same values for objects and Blocks with the additional BLOCK_BYREF_CALLER (128) bit of information supplied.
-
-So the __block copy/dispose helpers will generate flag values of 3 or 7 for objects and Blocks respectively, with BLOCK_FIELD_IS_WEAK (16) or'ed as appropriate and always 128 or'd in, for the following set of possibilities:
-	__block id                   128+3
-        __weak block id              128+3+16

-This is a replacement library for libgcc.  Each function is contained
