i tried the version of emacs today,
it still do not give me chance to input ,
gui emacs freeze when gdb showed the prompt again,
i tried to press key before it freeze,
the result is showed below:

[root@lpc src]# gdb ./emacs -q
Reading symbols from ./emacs...

Are you sure you want to change it? (y or n) [answered Y; input not from
terminal]

Thread 1 "emacs" hit Breakpoint 3, handle_one_xevent
(dpyinfo=0x555556112d50, event=0x7fffffffd710, finish=0x555555e9191c
<current_finish>, hold_quit=0x7fffffffda40) at xterm.c:18527
18527          if (dpyinfo->supports_xkb
(gdb) p xkey.state
No symbol "xkey" in current context.
(gdb) p dpyinfo->hyper_mod_mask
$1 = 0


i also tried to comment out that you say this :
         else if (dpyinfo->xkb_desc->names->vmods[i] ==
dpyinfo->Xatom_Hyper)
            dpyinfo->hyper_mod_mask |= vmodmask;

after rebuild,
the capital letter can normally insert with shift now.
hope it useful.

Thanks
