From the Delphi FAQ:
Question:
Where is the Windows API function CopyCursor defined in
32-Bit versions of Delphi and C++ Builder?
Answer:
While the call is documented in the Win32 help file, the
function is simply mapped to the Windows API function
CopyIcon(). Note that the 32 bit version of CopyIcon
does not take a hInstance parameter.
Add function. Sometimes I don't understand MSDN. This function is
available on Windows XP and Server 2003, but the SDK is supposed to

(handler_pipe::create): Rename from make_pipe. Change arguments to accept
fhandler_pipe array. Accommodate fifos.
(pipe): Rework to deal with fhandler_pipe::create changes.
(_pipe): Ditto.
* select.cc: Use individual device_specific types throughout rather than
indexing with obsolete device number.
(set_bits): Use is_socket call rather than checking device number.
* shared_info.h (CURR_MOUNT_MAGIC): Update.
(conv_to_win32_path): Reflect addition of device argument.
* syscalls.cc (mknod_worker): New function.
(open): Use build_fh_name to build fhandler.
(chown_worker): Detect if this is an 'auto' device rather than an on-filesystem
device and handle appropriately.
(chmod_device): New function.
(chmod): Detect if this is an 'auto' device rather than an on-filesystem device
and handle appropriately. Use chmod_device to set mode of in-filesystem
devices.
(stat_worker): Eliminate path_conv argument. Call build_fh_name to construct
fhandler. Use fh->error() rather than pc->error to detect errors in fhandler
construction.
(access_worker): New function pulled from access. Accommodate in-filesystem
devices.
(access): Use access_worker.
(fpathconf): Detect if this is an 'auto' device rather than an on-filesystem
device and handle appropriately.
(mknod_worker): New function.
(mknod32): New function.
(chroot): Free normalized path -- assuming it was actually cmalloced.
* tty.cc (create_tty_master): Tweak for new device class.
(tty::common_init): Ditto.
* winsup.h (stat_worker): Remove.
(symlink_worker): Declare.
* exceptions.cc (set_process_mask): Just call sig_dispatch_pending and don't
worry about pending_signals since sig_dispatch_pending should always do the
right thing now.
(sig_handle): Reorganize SIGCONT handling to more closely conform to SUSv3.
* pinfo.h: Move __SIG enum to sigproc.h.
(PICOM_FIFO): New enum element.
(_pinfo): Remove 'thread2signal' stuff throughout class.
(_pinfo::commune_send): Make varargs.
(_pinfo::sigtodo): Eliminate.
(_pinfo::thread2signal): Ditto.
* signal.cc (kill_worker): Eliminate call to setthread2signal.
* sigproc.cc (local_sigtodo): Eliminate.
(getlocal_sigtodo): Ditto.
(sigelem): New class.
(pending_signals): New class.
(sigqueue): New variable, start of sigqueue linked list.
(sigcatch_nonmain): Eliminate.
(sigcatch_main): Eliminate.
(sigcatch_nosync): Eliminate.
(sigcomplete_nonmain): Eliminate.
(pending_signals): Eliminate.
(sig_clear): Call signal thread to clear pending signals, unless already in
signal thread.
(sigpending): Call signal thread to get pending signals.
(sig_dispatch_pending): Eliminate use of pending_signals and just check
sigqueue.
(sigproc_terminate): Eliminate all of the obsolete semaphore stuff. Close
signal pipe handle.
(sig_send): Eliminate all of the obsolete semaphore stuff and use pipe to send
signals.
(getevent): Eliminate.
(pending_signals::add): New function.
(pending_signals::del): New function.
(pending_signals::next): New function.
(wait_sig): Eliminate all of the obsolete semaphore stuff. Use pipe to
communicate and maintain a linked list of signals.
* sigproc.h: Move __SIG defines here. Add __SIGPENDING.
(sig_dispatch_pending): Remove "C" specifier.
(sig_handle): Accept a mask argument.
* thread.cc: Remove signal handling considerations throughout.
