30 Some Linux errnos (EPROCLIM, EDOTDOT, ERREMOTE, EUCLEAN, ENOTNAM,
31 ENAVAIL, EISNAM, EREMOTEIO, ENOMEDIUM, EMEDIUMTYPE) have no Solaris
32 equivalents. I return EINVAL in that case, which is very wrong. If
33 someone suggest a better value for them, you're welcomed.
34 On the other side, Solaris ECANCELED and ENOTSUP have no Linux equivalents,
