 	include/limits.h: revision 1.45
 
 limits.h: Define PTHREAD_STACK_MIN and tidy up comments.
 
 Define this to be 4096, which is (as far as I can tell) the smallest
 possible page size on any architecture NetBSD supports.  This should
 be MIN_PAGE_SIZE instead, but I don't think that is exposed in any
 way that doesn't badly pollute the namespace.  We should maybe have a
 __MIN_PAGE_SIZE defined in some header file exposed to userland.
 
 Of course, applications actually need to allocate at least
 sysconf(_SC_THREAD_STACK_MIN) = getpagesize() bytes, which may be
 larger than PTHREAD_STACK_MIN.
 
 The various feature flags (dates) like _POSIX_THREAD_ATTR_STACKADDR
 are defined (or not defined) by unistd.h, not by limits.h, so there's
 no value in mentioning them here -- and the comment is wrong about
 most of them (we have implemented _POSIX_THREAD_ATTR_STACKADDR, for
 example).
