The last patch #6 (soon on Mikolaj web site) supports GDB/MI and
annotations level 3. It also provides hooks for a future
implementation based on an interface with only GDB/MI.

VimGDB level 3 mode does that: accessing MI from the CLI. The
"As an interum" may mean that this scheme will be obsoleted some time
and that the implementation based on an interface with only GDB/MI
will be required. This is not quite clear and may depend on how Emacs
developers implement GDB/MI.

BTW, my mail titled "Implementing a Gdb interface with GDB/MI" that I
sent more than one month ago is mostly all wrong and adding to the
confusion on GDB interfaces. I am sorry about that. There are actually
two interfaces to GDB, the CLI and MI. When using MI you are not
supposed to use any annotation at all (this is not written anywhere,
just deduction). You can use the "interpreter-exec" command to access
MI commands from the CLI and vice-versa.

VimGDB requires a lot of testing. When it is included among the other
patches in a future development release, testing can start being more
exhaustive. Meanwhile, all problem reports are very much welcome.
