[Boost-users] [range] From 1.33.0 gives new warning vs 1.32

I had some code that with 1.32 compiled fine when compiled with
warnings as errors, but now with 1.33 I get:

cc1plus: warnings being treated as errors

Compiled with gcc 3.2.3 under Linux,

perhaps something like this is needed?

Thanks

Kevin
