[Flex-devel] filter_apply_chain() unused variable

[Michael W. B. <mb...@ii...>]

Hello,

The variable r in flex's filter_apply_chain() is not needed.
https://github.com/westes/flex/blob/master/src/filter.c#L175

It was recently removed from OpenBSD's in-tree version of flex.
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/lex/filter.c.diff?r1=1.8&r2=1.9&sortby=date&f=h

I'm posting it here in case it's considered useful.
