Posix threads

[Hal Murray]

I'm looking for cruft to clean up.

If we have pthreads, will we also have pthread_attr_getstacksize and 
pthread_attr_setstacksize?

http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_attr_setstack
size.html says:

The pthread_attr_getstacksize() and pthread_attr_setstacksize() functions are 
marked as part of the Threads and Thread Stack Size Attribute options.

The restrict keyword is added to the pthread_attr_getstacksize() prototype 
for alignment with the ISO/IEC 9899:1999 standard.

I can't figure out if that means somebody could implement Threads without 
implementing Thread Stack Size.  Or even if they can, would anybody actually 
do it?
