Are you running Solaris 11 11/11 (build 175b)?
% grep CLOEXEC /usr/include/sys/fcntl.h
#define O_CLOEXEC 0x800000 /* open() sets the close on exec flag */
#define F_DUPFD_CLOEXEC 47 /* Duplicate fildes and set close-on-exec */
#define F_DUP2FD_CLOEXEC 48 /* Dup fd at 3rd arg and set close-on-exec */
#define FD_CLOEXEC 1 /* close on exec flag */
and "man fcntl" shows them as well. They were added in snv_153 in the same
changeset as open's O_CLOEXEC flag, so wouldn't be in S11 Express 2010.11
(151a).

Does it have F_DUP2FD? According to the CR for that change, both F_DUPFD &
F_DUPFD_CLOEXEC are defined by POSIX, but F_DUP2FD & F_DUP2FD_CLOEXEC are
non-standard extensions.
