Two uninitialized variables in cut.c may produce weird results. Do
AT&T's compilers initialize stack variables to zero?
There is also some junk code floating around and, finally, the holly
'cannot open' message...

Lint output:
================
cut.c(72): warning: r may be used before set
cut.c(75): warning: num may be used before set
cut.c(20): warning: d unused in function main
fclose returns value which is always ignored
diagl defined( cut.c(177) ), but never used
optarg used( cut.c(53) ), but not defined
optind used( cut.c(63) ), but not defined
