Excellent slides. Many thanks for doing this. > > I have not yet committed any patches to the branch--at present it is > just a copy of the trunk.

I have a question: I suspect that in concreteness you would prefer declarations in GCC headers have a C++ linkage, as opposed to C linkage -- except where for interoperability with common runtime systems, we want the declarations to have C linkage (e.g. in libgcc for example). Am I correct? The reason I'm asking is that a fresh build o gcc-in-cxx dies on my machine with complains that `program' has conflicting declarations: once in libcpp.h as having C++ linkage, once in toplev.h with a C declaration. It is the tradition in modern C++ to avoid having many `sources' for the same declaration. -- Gaby
