IIRC the C language standard requires that global variables are automatically
initialized to 0 if not explicitly initialized. Personally I would prefer an
explicit init to 0 here just for clarity (e.g. to avoid the confusion caused in
this ticket).
This code obviously depends on the implicit init to 0 of the global variable
gdb_actual_connections:

** [tickets:#256] `gdb_actual_connections` is never initialized?**

Looks like the variable `gdb_actual_connections` is never initialized but is
read from and affects execution.
`src/server/gdb_server.c: 120`.
