#2975: [PATCH] Allow attachment saving on the FreeBSD's msdosfs Comment (by pdmef): My <sys/errno.h> (OS X) conditionally defines EOPNOTSUPP as ENOTSUP and comments on EOPNOTSUPP as being socket-related. Therefore, I think using ENOTSUP should be used (they're identical on FreeBSD too). -- Ticket URL: <http://dev.mutt.org/trac/ticket/2975#comment:1>
