(dev_storage): Ditto for /dev.
* devices.cc: Regenerate.
* fhandler.cc (fhandler_base::open_null): New method to open a fake
\Device\Null handler.
(fhandler_base::open): Fix formatting. Change O_ACCMODE test to a
switch statement. Simplify a test which still tested for a now unused
create_disposition.
* fhandler.h (fhandler_base::open_null): Declare.

rather than setting nohandle.
(fhandler_netdrive::close): New method.

call. Create valid key for HKEY_CURRENT_CONFIG by mapping to real key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Hardware Profiles\Current.
(fhandler_registry::open): Set nohandle only when using pseudo registry
handle.
* fhandler_virtual.cc (fhandler_virtual::opendir): Call open rather
than just setting nohandle here.
* fhandler_virtual::fstatvfs): Set ST_RDONLY fs flag.
* globals.cc (ro_u_null): New readonly UNICODE_STRING for \Device\Null.
* path.h (path_conv::set_path): Revert previous change caring for
wide_path.
(dev_storage): Map /dev and /dev/windows to \Device\Null.

without O_CREAT flag. Explain why. Create \Device\Null handle if
/dev/ doesn't actually exist.
(fhandler_dev::close): Drop nohandle case.
(fhandler_dev::fstatvfs): Drop nohandle check. Test for fs_got_fs
instead. Set ST_RDONLY fs flag for simulated /dev.
(fhandler_dev::opendir): If /dev doesn't exist, call open() to create
fake \Device\Null handle. Don't set nohandle. Set dir_exists
correctly.
(fhandler_dev::rewinddir): Call fhandler_disk_file::rewinddir only if
/dev is a real directory.
* fhandler_disk_file.cc (fhandler_disk_file::opendir): If called for
the cygdrive dir, call open() to create fake \Device\Null handle.

Don't set nohandle.
(fhandler_cygdrive::open): Create \Device\Null handle.
(fhandler_cygdrive::close): Remove.

* fhandler_windows.cc (fhandler_windows::open): Create \Device\Null
handle.

"message arrived".

(fhandler_windows::select_except): Ditto.
warnings between regparm definitions and declarations.

setting of l_opt for only x86_64.
* spawn.cc (child_info_spawn::worker): Remove unused 'pid' variable.
* thread.cc (verifyable_object_isvalid): Temporarily define as
non-inline with gcc 4.7+, regardless of target.
(mainly in fhandler*) start fixing gcc 4.7.2 mismatch between regparm
definitions and declarations.
* gendef: Define some functions to take @ declaration to accommodate _regN
defines which use __stdcall.
* gentls_offsets: Define __regN macros as empty.
* autoload.cc (wsock_init): Remove unneeded regparm attribute.
* winsup.h (__reg1): Define.
(__reg2): Define.
(__reg3): Define.
* advapi32.cc (DuplicateTokenEx): Coerce some initializers to avoid warnings
from gcc 4.7.2.
* exceptions.cc (status_info): Declare struct to use NTSTATUS.
(cygwin_exception::dump_exception): Coerce e->ExceptionCode to NTSTATUS.

warnings.
(fhandler_dev_clipboard::read): Ditto.
* fhandler_dev.cc (fhandler_dev::readdir): Set st_ino to device number.
* syscalls.cc (fhandler_base::stat_fixup): Ditto. Fix link count for
CD-ROM devices. Fix typo in comment.
(device::dev_on_fs): Remove unneeded bit field. Just make a normal boolean.
(device::exists): Redefine function.
* devices.in: Move previous functions earlier since they are now only defined
static. Rename some functions due to an as-yet unresolved bug in gendevices.
Rename posix part of internal-only devices with a double-slash. gendevices
will eventuall translate that to a ":".
(device::parse): Rework to use dev pointer and dev_storage_end.

* devices.h (device::exists_func): New member function pointer,

to device::exists.
* devices.cc: Regenerate.
* devices.h (device::noexpose): New field.
(device::dev_on_fs): Make a bit field.

(dev_storage_size): Ditto.
(dev_storage): New declaration.
(dev_storage_end): Ditto.
* devices.in: Mark /dev/ptym*, /dev/com*, /dev/pipe, /dev/fifo, and "/dev" as
"no expose".
* fhandler.h (fhandler_dev::lastrealpos): Delete declaration.
(fhandler_dev::devidx): Declare new field.
* fhandler_disk_file.cc: Move fhandler_dev functions into fhandler_dev.cc.
* fhandler_dev.cc: Add includes needed for functions moved from
fhandler_disk_file.cc.

(dev_storage_size): Define size of array to scan.
(fhandler_dev::fhandler_dev): Move here from fhandler_disk_file.cc.
(fhandler_dev::opendir): Ditto.
(fhandler_dev::readdir): Just check devidx for non-NULL to determine when to go
to disk for /dev content. Use dev_storage rather than ext_dev_storage.
Iterate over dev_storage using devidx pointer. Use accessor functions rather
than raw references to the device struct. Only increment dir->__d_position
when we are actually going to be returning something. Add debug_printf for
exit.
(fhandler_dev::rewinddir): Set devidx as appropriate depending on whether
there's a /dev on disk or not.
* gendevices: Don't mark dev_storage static but do put it in the _RDATA
section.
* path.cc (path_conv::check): Use new "device::expose()" function to decide to
forbid programs from referencing internal device types.
