another similar case of missing `defvar`s plus a bit of dead code.

it to max_align_t. This copies from Gnulib’s c-stack.c, and works
around a portability bug in draft glibc 2.34, which no longer
defines SIGSTKSZ when _GNU_SOURCE is defined.
WINDOW arg nil will always create a new window regardless of the value
returned by 'frame-root-window' that is nondeterministic - it returns
an internal window when there are more than 1 window on the frame/tab,
otherwise it returns a live window that was reused between different tabs
(bug#46904)
(tab-prefix-map): Bind "u" to 'tab-undo'.
