Re: save RMan [-> tiff] in gv

It looks like it might work on a next.

For in the file '.../src/lib/mg/rib/mgrib.c' we see:

    /* this will make sure there's nothing left in the rib file */
    /* we cannot use ftruncate because it generates an error on sgi*/
    /*ftruncate(fileno(_mgribc->rib), 0);*/
    if (lseek(1, (off_t)0, 0) == (off_t)0 && ftruncate(1, (off_t)0)  
== -1)
	perror("ftruncate");
