Regression compile of emacs-27.1.tar.gz

[John Conover]

I need to compile emacs-27.1.tar.xz, (the standard for Debian 11,
Bullseye,) on Debian 12, Bookworm, and prefer to compile the gnu
sources:

    Source: https://ftp.gnu.org/gnu/emacs/emacs-27.1.tar.xz:

        Compiler error:

            sysdep.c:1819:22: error: variably modified ‘sigsegv_stack’ at 
file scope
             1819 | static unsigned char sigsegv_stack[SIGSTKSZ];

Can this sigsegv_stack statement in sysdep.c be replaced with the same
statement from emacs-29.x.tar.xz, (which is quite different, but
compiles.)

Any consequences for that single change?

    Thanks,

    John
