for a stackdump and to avoid recursion.

2012-02-11 Corinna Vinschen <corinna@vinschen.de>
* 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.

be never longer than MAX_PATH. Don't prepend native NT path prefix

try to load user's classes hive.

userprofile_env_buf to MAX_PATH. Add comment.
2012-02-10 Christopher Faylor <me.cygwin2012@cgf.cx>

things kludgy, set ctty to -2 here as a special flag, and...

2012-02-10 Christopher Faylor <me.cygwin2012@cgf.cx>

become controlling tty if there is no controlling tty.

early EOF in caller.

separate calls to __pthread_cond_wait_init and (*cond)->wait to be
able to initialize cond before accessing its clock_id member.
(pthread_cond_wait): Ditto (more or less).
2012-02-08 Christian Franke <franke@computer.org>
* include/sys/wait.h: Remove C++ inline functions for `union wait'.
For C++ use `void *' as __wait_status_ptr_t instead. This is less type
safe but fixes compile error on `wait(NULL)'. Remove extra `;'.
