- also change the handling of default_newlib_reent_check_verify to
be the same as other default variables in configure.host
- regenerate newlib/configure
- Though this rarely happens, sometimes the first printing of non-
cygwin process does not displayed correctly. To fix this issue,
the code for waiting for forwarding by master_fwd_thread is revised.
If we had architecture-specific exception bits, we could just set them
to match the processor, but instead ieeefp.h is shared by all targets
so we need to map between the public values and the register contents.

This makes the fpsetround function actually do something rather than
just return -1 due to the default 'fall-through' behavior of the switch
statement.

Following Linux, allow the pathname argument to be an empty string if
the AT_EMPTY_PATH flag is specified. In this case the dirfd argument
can refer to any type of file, not just a directory, and the call
operates on that file. In particular, dirfd can refer to a symlink
that was opened with O_PATH | O_NOFOLLOW.
Following Linux, allow the pathname argument to be an empty string,
provided the dirfd argument refers to a symlink opened with
O_PATH | O_NOFOLLOW. The readlinkat call then operates on that
symlink.
Commit 283cb372, "Cygwin: normalize_win32_path: improve error
checking", required a prefix '\\?\' or '\??\' in the source path to be
followed by 'UNC\' or 'X:\', where X is a drive letter. That was too
restrictive, since it disallowed the paths '\\?\X: and '\??\X:'. This
caused problems when a user tried to use the root of a drive as the
Cygwin installation root, as reported here:
https://cygwin.com/ml/cygwin/2020-01/msg00111.html
Modify the requirement so that '\??\X:' and '\\?\X:' are now allowed
as source paths, without a trailing backslash.
- In octave gui, sometimes state mismatch between real pty state
and state variable occurs. For example, this occurs when 'ls'
command is executed in octave gui. This patch fixes the issue.
- After commit e1a0775dc0, the problem
reported in https://www.cygwin.com/ml/cygwin/2020-01/msg00093.html
occurs. For Gnu scren and tmux, calling FreeConsole() on pty close
is necessary. However, if FreeConsole() is called, cygwin setup
with '-h' option does not work. Therefore, the commit
e1a0775dc0 delayed closing pty.
This is the cause of the problem above. Now, instead of delaying
pty close, FreeConsole() is not called if the process is non cygwin
processes such as cygwin setup.
- The console with 24bit color support has a problem that console
mode is changed if cygwin process is executed in cmd.exe which
started in cygwin shell. For example, cursor keys become not
working if bash -> cmd -> true are executed in this order.
This patch fixes the issue.
- In Win10 1809, the cursor position sometimes goes out of screen
by clear command in console. This seems to be caused by escape
sequence CSI3J (ESC[3J). This happens only for 1809. This patch
is a workaround for the issue.
- Special function keys such as arrow keys or function keys do not
work in ConEmu with cygwin-connector after commit
6a06c6bc8f. This patch fixes the
issue.
- PTY code which support pseudo console has a problem that causes
handle leaks. Four of these are bug in pty code, and the other
one seems to be a bug of Windows10. ClosePseudoConsole() fails
to close one internal handle. This patch fixes the issue.
- If two PTYs are opened in the same process and the first one
is closed, the helper process for the first PTY remains running.
This patch fixes the issue.
- The slowing down issue of X11 forwarding using ssh -Y, reported
in https://www.cygwin.com/ml/cygwin/2019-12/msg00295.html,
is due to the change of select() code for pty in the commit
915fcd0ae8. cygthread::detach()
takes at most about 10msec because Sleep() is used in the thread.
For this issue, this patch uses cygwait() instead of Sleep() and
introduces an event to abort the wait. For not only pty, but pipe
and fifo also have the same problem potentially, so this patch
applies same strategy to them as well.
Though our implementation of cpu sets doesn't need it, software from
Linux environments expects this definition to be present. It's
documented on the Linux CPU_SET(3) man page but was left out due to
oversight.

Add that flag to the pipe type argument when creating the Windows
named pipe. And add a definition of that flag to ntdll.h (copied from
/usr/include/w32api/ddk/ntifs.h).
- Even with commit fe512b2b12, pty
still has a problem in ESC[?3h and ESC[?3l handling if invalid
sequence such as ESC[?$ is sent. This patch fixes the issue.
In the two helper functions that _dcvt calls for 'f' and 'e' mode, if
there are no digits to display after the decimal point, don't add one.

Leading zeros after the decimal point should not count
towards the 'ndigits' limit.
This makes gcvt match glibc and the posix gcvt man page.

Both functions were introduce with Windows 7 only, so we need to
autoload them for the sake of Vista/2008.
