[syslog-ng] [PATCH] [1.9.5] address flex warning and suboptimal distclean target

[Roberto Nibali]

Hello,

The attached patch fixes following two things:

1. #define YY_NO_UNPUT   1 is an undocumented feature of flex and has
    been obsoleted in recent flex versions. So this is a void operation.
    The correct way of dealing with the compiler warning is to add
    %option nounput as flex directive.

2. cfg-lex.c is autogenerated during the make compile process. However
    it is never removed, especially not for the distclean target. IMHO
    this is not so clean, so I've added cfg-lex.c to the list of the
    to-be-removed files.

Please consider applying.

Cheers,
Roberto Nibali, ratz
