This looks like an error in your code.  The spec says:

> Minimum size in bytes of thread stack storage.

It is meant to be the minimum value that the system can give for a thread 
stack.  The purpose of this constant is for languages that do their own stack 
management bit some chain of activation records of segmented stacks, but want 
to use pthreads for threading, so that they can allocate the smallest possible 
stack that allows pthread cleanup to work.  

Using it from C code is very likely to be a mistake.
