Re: [patch] Dummy first call to gdb_has_a_terminal()

[Balazs Kezes <rlblaster@gmail.com>]

Okay, now I checked this more thoroughly. initalize_all_files() in init.c
calls tui initialization functions which mess up the terminal and call
gdb_has_a_terminal() afterwards. So it must be called before this function.

The other way (start gdbtui /bin/echo, switch to gdb, run) seems to work
after the gdb_has_a_terminal is added to the initialize_stdin_serial().

So here is my revised patch:

Changelog:
       * inflow.c (initialize_stdin_serial): Added gdb_has_a_terminal to
       actually save all the tty settings.
       * top.c (gdb_init): Move initialize_stdin_serial before
       initialize_all_files because it assumes it has been already called.
