I guess Solaris (version?) doesn't implement the version of POSIX that has
O_CLOEXEC defined. I think that's the 2008 version, Issue 7.

The purpose of the builtin is to query and set the file descriptor flags
the system supports, and those flags are the ones defined for open(2), so
we really need to use O_CLOEXEC if it's available and skip it if it's not.
I'll see about making those changes for the next devel branch push.
