I'm having big problems at using gdb, I tried various combinations
(using gdb --annotate=3, gdb -i=mi) but gdb is always mibehaving.

For example this is what I see in the *gud* buffer with M-x gbd -> gdb 
--annotate=3:
---------------------------------------------------8<-------------------

                                                                                
    pre-prompt
       prompt
[...]                                                                           
         post-prompt
error-begin
Undefined command: "1-inferior-tty-set".  Try "help".
pre-prompt
       prompt
---------------------------------------------------8<-------------------

If I try to use gdb -i=mi I got something of the kind:
---------------------------------------------------8<-------------------
(gdb) file hello
r
b main
Breakpoint 1 at 0x8048542: file hello.c, line 5.
(gdb) r
n
n
(gdb) 
---------------------------------------------------8<-------------------

No prompt is shown and the pointer in the source code buffer is not
updated as I step over/into.



Finally if I don't specify the gdb flags I got something of the kind:

So I'm badly stucked here, up to the point that I cannot to debug code
from emacs.

Can you give some guidance, or at least provide some hint regarding
how should I debug this problem? Up to now I didn't find anything
useful by googling, help is much appreciated.

Regards.
