gcj: how to disable 'Discouraged redundant use of...' warning.

["miko mmm" <miko3l@xxxxxxxxx>]

I would like to disable warnings about 'Discouraged rendundant uses of
public/static/final...' because I'm compiling code with thousands of
such reduandant uses (sdljava). But I want to see all other warnings.

Is it posssible ?
