mentions that you can increase the history size to being unbound by invoking
"set history size unlimited". This command is not working though.

This works for me.

Trying with:

  #> (HISTSIZE=2 ./gdb/gdb)

I see that GDB only keeps 2 commands in the history.  However, if I "set
history size unlimited", it starts keeping more and more commands as I type.

It is worth noting that I tried our git master HEAD.

Ah, ok, then it seems to be fixed in the HEAD.
In my 7.5 version it says "No symbol table loaded. Use the >>file<<-command",
or if started with an executable, "No symbol 'unlimited' in current context.".
So it seems GDB tries to resolve "unlimited" as symbol in the debugee here.
I probably should have posted this along with the report.

C-s is shadowed by the terminal's flow control.  Use "stty" to change this
behavior if you want.  You can use "stty -a" to see all keybindings that are
reserved by the terminal.

In order to "fix" this bug, you can either:

(a) Disable the flow control, by using "stty -ixon"

(b) Rebind the STOP flow control, by using "stty stop ^K", where "^K" means C-k
(you can use whatever key you want).

After that, you will be able to use forward-search-history as usual.  As a side
note, this affects readline programs (like bash), and not GDB alone.
