For a variety of reasons I'd like to be able to compile (on a DOS machine
with Turbo C) with a stack that is larger than the usual 4kB. The manual
(yes, I *have* read the FM) says I should simply set _stklen (defined in
dos.h) to the desired value. I just can't find out where. If I put e.g.

  _stklen = 10000;

at the start of main (), nothing happens, i.e. when I deliberately cause
a stack overflow by some silly recursion, the number of times my
stack-consuming function can call itself before triggering the `Stack
overflow!' run-time error is always the same. (I can even make _stklen 0
if I like.) Actually, I don't understand how a program would be able to
change its own stack size at run time. Is this really what happens (or,
in my case, doesn't happen)? Who has a working example of how to do this?
