Having yet another system-dependent macro is something I wanted to avoid.

Also, a static compile-time limit would have trouble in the face of users 
and sysadmins who can change the stack limits with `ulimit' and similar 
facilities.  Even with DJGPP, you can modify the maximum stack size of a 
program to an arbitrarily large or small value with a special utility.

Perhaps setting the limit you suggested to a much smaller value, like 
10KB, say, would be a better and easier way of solving this.  IIRC, last 
time the alloca issue was discussed, the consensus about the maximum size
of safe off-stack allocations was that it should be a few KB.
