The flex binary package comes with examples under /usr/share/doc/flex/examples/fastw .

These were from 2016 and don't work as expected with current gcc and
flex.

Attached patch fix these issues.
 * need "int" for main
 * need tailing "%%"

I think these may have been OK with old tool chain but they cause
trouble these days.

Now these can be compiled with

```
gcc -lfl mywc.c -o mywc
for f in 1 2 3 4 5; do
flex wc$f.l
gcc -lfl lex.yy.c -o wc$f
rm -f lex.yy.c
done
```

These example files are from upstream source under

Hi,

Oops, "-lfl" may have been redundant...
