0 /* obstack.h - object stack macros
43 them before using any obstack macros.
45 Each independent stack is represented by a `struct obstack'.
46 Each of the obstack macros expects a pointer to such a structure
63 With obstacks, you can work differently.  Use one obstack for all symbol
64 names.  As you read a symbol, grow the name in the obstack gradually.
99 	Exactly one object is growing in an obstack at any one time.
100 	You can run one obstack per control block.
102 	Because of the way we do it, you can `unwind' an obstack
