If ENABLE_BUILD_WITH_CXX is defined, then GCC itself is built with C++, and we want a C++ signature for functions. If it is not defined, then GCC itself is not built with C++, and we want (and must have) a C signature. I suppose we would decide that fancy_abort always uses a C signature, but that seems odd. Ian
