I have not compiled this code - but I bet it would fix Jeff Solof's
problems. Essentially - the flag bits in the princap file are BSD based
specific and cannot simply be mapped to POSIX.
Someone should compile lpd and try it on Jeff Solof's machine with these
changes.
(Either that of if someone can find the changes that were made to
/mit/opssrc/lpd/....)
