"lint" missed some other problems:
exit() misdeclared
lseek() return comparison against NULL is wrong
fgetc() return not compared against EOF
<sys/file.h> L_SET should not be used in an application
...

"What is wrong with this program?" reminded me of the "What is wrong
with this picture?" puzzles in children's books.  Often my reaction
was, "What is RIGHT with this picture?".
