<sigh> In my .profile, and in a wretched case statement which depends
on OS, SHELL, phase of moon, and barometric pressure,  I have
various statements such as:

    rsWINCH() { echo "Caught SIGWINCH">&2;  resize; }
    trap rsWINCH WINCH

Bash is pretty good at handling SIGWINCH and setting LINES and COLUMNS.
Other shells do less well.  In some cases I parse the output of
"stty -a" and set LINES and COLUMNS myself.  On OS/390 I don't
have a working "resize", but someone just told me of one, and I'm
trying to compile it as I type.  If there's a standard way to do
all this, I don't know it.  </sigh>

And Lynx's behavior is reported to depend on whether you're using
ncurses or slang or whatever.  My observation is that Lynx as I
compile it knows only the settings of LINES and COLUMNS when started,
and is completely insensitive to SIGWINCH.  YMMV.
