* ioext.c (scm_primitive_dup2): return the new file descriptor instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup is convenient. (scm_fdopen): bug fix: don't try to make port unbuffered until its stream has been set. (scm_duplicate_port): deleted, there's now an implementation in boot-9.scm. (scm_primitive_dup2): do nothing if newfd == oldfd. * boot-9.scm (dup->port, dup->inport, dup->outport, dup->fdes, dup, fdes->inport, fdes->outport, port->fdes): new procedures. (duplicate-port): was a C primitive, now it's here. (move->fdes): allow the first argument to be a file descriptor. Return the modified port or file descriptor (was unspecified.)
