* miscfuncs.cc (DEFAULT_STACKSIZE): Remove.
(CygwinCreateThread): Simplify code by assuming that now stack-related
input values are undefined. Set stack protection to PAGE_READWRITE,
as is default on Windows. Add lengthy comment to explain POSIX
guardpage.
* thread.cc (pthread_attr::pthread_attr): Initialize stacksize as
PTHREAD_DEFAULT_STACKSIZE. Initialize guardsize as
PTHREAD_DEFAULT_GUARDSIZE.
* thread.h (PTHREAD_DEFAULT_STACKSIZE): Define. Add comment to explain.
(PTHREAD_DEFAULT_GUARDSIZE): Define.
