Subject: Re: [OMPI devel] flex warning from flex-2.5.4
From: Ralph Castain (rhc_at_[hidden])

We get that everywhere, unfortunately - it comes from flex and is outside our control as the file it complains about is actually generated by flex itself. Unfortunately, flex is no longer maintained, and so nothing has been done to correct it.
