[LI Daobing <lidaobing@gmail.com>]

Package: cpp-4.0-doc
Version: 4.0.2-3
Severity: minor

Hello,

you can see[1] that cpp support -O, -O[1-9], -Os options, and these
options are meanful. but this is not documented in man page[2] and
info[3].

man page belongs to cpp-4.0, need I clone this bug?

$ cpp -dM /dev/null | grep OPT
$ cpp -dM -O /dev/null | grep OPT
#define __OPTIMIZE__ 1
$ cpp -dM -Os /dev/null | grep OPT
#define __OPTIMIZE__ 1
#define __OPTIMIZE_SIZE__ 1
$ cpp -dM -O2 /dev/null | grep OPT
#define __OPTIMIZE__ 1
