instead of decimal. Also, don't use the `l' modifier for something
that has just been cast to `int' anyway.
Remove various bogus pathnames to look up rsh(1) at. Our rsh is in
/usr/bin, but never in /usr/usb, nor would it ever be called remsh...
Also, if it hasn't been found there, use execlp() to look it up. the
latter is required for `weird' environments like a fixit floppy where
the regular /usr/bin hiearrchy is not avaiable. tar should probably
do it similar to dump/restore, and use rcmd(3) instead of forking an
external process.
