[PATCH] Cygwin: termios: Set ECHOE, ECHOK, ECHOCTL and ECHOKE by default.

[Takashi Yano via Cygwin-patches]

- Backspace key does not work correctly in linux session opend by
  ssh from cygwin console if the shell is bash. This is due to lack
  of these flags.

[PATCH] Cygwin: pty: Call FreeConsole() only if attached to current pty.

[Takashi Yano via Cygwin-patches]

- After commit 071b8e0cbd4be33449c12bb0d58f514ed8ef893c, the problem
  reported in https://cygwin.com/pipermail/cygwin/2020-May/244873.html
  occurs. This is due to freeing console device accidentally rather
  than pseudo console. This patch makes sure to call FreeConsole()
  only if the process is attached to the pseudo console of the current
  pty.

[PATCH] libc: Replace i386/sys/fenv.h symlink with an #include shim

[David Macek via Cygwin-patches]

Same reasoning as fbaa0967.

Excuse my ignorance, but is this acceptable?  I'm not sure
what actually happens with these files, but it'd be nice to
get rid of the last symlink in the repo.
