Oh, last-rhepl. That's different. Those sources are frozen and will never 
change. You can make the change by hand instead. See 
http://sources.redhat.com/ml/ecos-patches/2002-10/msg00080.html

That is a known conflict between the sources you are using and newer GCCs. 
That problem is fixed in the current sources, i.e. covered by the GPL, not 
RHEPL. You could fix it by hand by removing the initializer in flag.cxx. ( 
i.e. change
Cyg_Flag::Cyg_Flag( Cyg_FlagValue init = 0 )
to
Cyg_Flag::Cyg_Flag( Cyg_FlagValue init )

in flag.cxx, and similarly for the other functions that crop up (e.g. 
maskbits and setbits in flag.cxx at least). Note that's just the .cxx file 
you change, not the .hxx.

This is the risk and penalty of using the older RHEPL sources, sorry.

Or you could revert to a 2.95.x series GCC.
