+
+ Fix handling of closed stdin/stdout/stderr on mingw.
+ * lib/w32spawn.h: Include unistd.h.
+ (dup_noinherit): Return -1 if the old handle is invalid. Allocate new
+ file descriptor with O_NOINHERIT flag.
+ (fd_safer_noinherit): New function, based on fd-safer.c.
+ (dup_safer_noinherit): New function, based on dup-safer.c.
+ (undup_safer_noinherit): New function.
+ * lib/execute.c (execute) [WIN32]: Use dup_safer_noinherit instead of
+ dup_noinherit. Use undup_safer_noinherit instead of dup2 and close.
+ * lib/pipe.c (create_pipe) [WIN32]: Likewise. Use fd_safer_noinherit
+ instead of fd_safer.
+ * tests/test-pipe.c: Include <windows.h>.
+ (child_main) [WIN32]: Test the handle of STDERR_FILENO, not its close() result.
+
+ * tests/test-pipe.c (child_main, parent_main): New functions, extracted
+ from main.
+ (test_pipe): Pass an extra argument for disambiguation.
+ (main): Invoke parent_main or child_main.
+
+ * tests/test-pipe.c (test_pipe): Pass slave_process = true argument
+ consistently.

+ test-pipe: fix mingw build
+ * tests/test-pipe.c (main): Avoid fcntl on mingw.

+
+ * modules/pipe-tests (Makefile.am): Fix typo.

+
+ error: fix mingw build
+ * lib/error.c (error, error_at_line): Avoid fcntl on mingw.
+ Reported by Bruno Haible.
+
+ error: avoid undefined use of stdout
+ * lib/error.c (error, error_at_line): Check that fd 1 is open
+ before flushing stdout. Avoids a crash on cygwin when libsigsegv
+ is handling faults and the close_stdout module wants to report the
+ detection of closed stdout as an error.
+

+
+ pipe: be robust in face of closed fds
+ * lib/pipe.c (create_pipe): Closed standard descriptors in parent
+ should cause child to misbehave.
+ * modules/pipe-tests: New module.
+ * tests/test-pipe.c: New file.
+ * tests/test-pipe.sh: New file.
+ Reported by Akim Demaille.

+
+ * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Guess it works on glibc systems.
+ Reported by anonymous kc.
