Yes. There are two relevant configure options: --enable-build-with-cxx and --enable-build-poststage1-with-cxx. Currently the first defaults to no and the second defaults to yes. The change in question would be making the first default to yes. > The VMS targets are not yet ready with build in C++ mode.

Sounds like you would need to have a C++ cross-compiler for VMS. What are the issues with making that work? Ian
