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

(pthread::thread_init_wrapper): Use __reent_t::init_clib to init local clib
storage and set std{in,out,err} appropriately.
(winpids::winpids): Rejigger to set pinfo_access.
* pinfo.cc (winpids::add): Try to open shared memory region with supplied
pinfo_access first, then default to readonly.
* fhandler_termios.cc (tty_min::kill_pgrp): When getting list of pids to work
with, suggest opening with PID_MAP_RW.
* signal.cc (kill_pgrp): Ditto.
* sigproc.cc (sig_send): Perform a write check on todo prior to attempting to
increment it. Return EACCES if we can't write to it.
* security.h (__sec_user): Add "access2" argument.
(sec_acl): Add "original" and "access2" arguments.
(sec_user): Add "sid2" and "access2" argument. Remove dependence on
allow_ntsec.
(sec_user_nih): Ditto.
* sec_helper.cc (__sec_user): Add "has_security" test.
Call sec_acl with new arguments, letting it handle original_sid.
(sec_acl): Add "original" and "access2" arguments. Handle original_sid
depending on flag but avoiding duplicates. Use "access2" for sid2.
* pinfo.cc (pinfo::init): Use security attributes created by sec_user
when creating the mapping.
* security.cc (create_token): Adjust arguments in call to sec_acl.
Call sec_user instead of __sec_user.
* syscall.cc (seteuid32): Adjust arguments in call to sec_acl. Remove
now unnecessary test. Remove useless conversions to psid.
* dcrt0.cc (dll_crt0_1): Call cygsid::init before pinfo_init.
* cygwin.din: Remove extraneous mallinfo definition.
* dcrt0.cc (quoted): Use strechr for efficiency.
* fhandler.cc (fhandler_base::write): Correctly use get_output_handle rather
than get_handle.
(fhandler_base::lseek): Use method for accessing name in debug output.
* pinfo.cc (pinfo_init): Initialize myself->gid.
(pinfo::init): Create the "access" variable, set it appropriately and use it to
specify the requested access.
* exceptions.cc (sig_handle_tty_stop): Add PID_MAP_RW in pinfo parent.
* signal.cc (kill_worker): Ditto for pinfo dest.
* syscalls.cc (setpgid): Ditto for pinfo p.
* exceptions.cc (early_stuff_init): Delete.
(init_console_handler): New function - top half of early_stuff_init.
(init_global_security): New function - bottom half of early_stuff_init.
(sig_handle): Avoid special hExeced test for SIGINT. Just terminate the
captive process.
(signal_exit): Add debugging output.
* fhandler_tty.cc (fhandler_tty_slave::open): Don't allocate a console if one
already seems to exist. Properly initialize ctrl-c handling if we do allocate
a console.
* winsup.h (early_stuff_init): Delete declaration.
(init_console_handler): New declaration.
(init_global_security): New declaration.
Accept an argument and calculate any extra links needed based on missing . and
.. entries.
(fhandler_disk_file::fstat_helper): Always call pc->ndisks_links() to calculate
the number of links.
* path.h (path_conv::ndisk_links): Declare.
