   4 Subject: fix build regression on archs with variable page size
   5
   6 commit 31fb174dd295e50f7c5cf18d31fcfd5fe5a063b7 used
   7 DEFAULT_GUARD_SIZE from pthread_impl.h in a static initializer,
   8 breaking build on archs where its definition, PAGE_SIZE, is not a
   9 constant. instead, just define DEFAULT_GUARD_SIZE as 4096, the minimal
  10 page size on any arch we support. pthread_create rounds up to whole
  11 pages anyway, so defining it to 1 would also work, but a moderately
  12 meaningful value is nicer to programs that use
  13 pthread_attr_getguardsize on default-initialized attribute objects.
