+Subject: [PATCH] fcntl: add constants FD_CLOEXEC, and O_CLOEXEC where
+ supported.
+
+Close #227.
+* ext/posix/fcntl.c (O_CLOEXEC): Default to `0` when not defined
+by underlying system so that it can be ORed successfully.
+(open): Note O_CLOEXEC in LDocs.
+(O_CLOEXEC, FD_CLOEXEC): Define as Lua constants.
+
+Signed-off-by: Gary V. Vaughan <gary@gnu.org>
