to avoid future problems.
(struct parse_thing): Change all justset to setbool for bool variables.

structure in parent process.

of case sensitivity on post-Windows 2000 systems.

lock object handle explicitely in case of called during fork. Add
comment to explain why.

* wincap.cc: Implement above element throughout.
* fhandler_disk_file.cc (fhandler_cygdrive::opendir): Rename flptst
to drive. Call new get_disk_type function rather than is_floppy and
check SMB drives with the NetUseGetInfo function. Explain why.

native NT device name.
(is_floppy): Remove.

Windows-provided stack rather than an own stack created in
CygwinCreateThread.
(struct thread_wrapper_arg): Rename commitsize to stacklimit.
(CygwinCreateThread): Rename commitsize to real_stacklimit.
WFMO. Drop debug output if process is not available. Set timeout to
0 instead. Document timeout 0 in WFMO comment.
(lf_getblock): Drop invalid F_POSIX lock type shortcut. Only return
overlap if event is not signalled. Fix comment.
in question == our ctty.
* syscalls.cc (setsid): Avoid two function calls.
* dtable.cc (dtable::dup_worker): Remove debugging.
* init.cc (search_for): Calculate for every new process rather than using
shared value.
(threadfunc_ix): Fill in for ever new process rather than sing shared value.
Change related casts throughout.
(thread_wrapper): Only do the thread change if the application provided
the stack. Otherwise, just use the Windows-provided stack. Set up
POSIX guardpage here, if necessary. Move related comment from
CygwinCreateThread here.
(CygwinCreateThread): Never allocate and set up own stack here. Just
compute stack size to reserve and use value in CreateThread call if
stack hasn't been provided by the application.
* collate.h: New header.
(__collate_range_cmp): Declare.

* nlsfuncs.cc (__collate_range_cmp): ...to here.

Change the way how the stack is commited and how to handle guardpages.
Explain how and why.

* exceptions.cc (stackdump): Rework to perform all operations needed for a
stackdump and to avoid recursion.
(exception::handle): Use simplified stackdump interface.
* sigproc.cc (signal::exit): Ditto. Delete now, uneeded declaration.
(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.
RLIMIT_STACK.
* registry.cc (get_registry_hive_path): Expect the user hive path to
be never longer than MAX_PATH. Don't prepend native NT path prefix
here. Add comment.

try to load user's classes hive.

modname. Search dll using modname.
__pthread_cond_dowait. Only check and potentially initialize cond and
mutex, drop call to (*cond)->wait.
