An obstack is a stack of objects. Basically obstacks are used as a
form of memory management which is in appropriate situations can be
more efficient and less difficult than malloc/free. See obstack.h.

GNU C can generate either (1) assembly code, which is passed to the
assembler to generate machine code, or (2) byte code, i.e. code for a
virtual machine, which can be interpreted by a byte-code interpreter.
>From what I understand, the support for byte code in gcc is not yet
complete -- in particular, I don't think anyone has written the
byte-code interpreter yet.
