Hi, Paolo, I've reverted the patch. This was intended to fix the broken bootstrap under --enable-build-with-cxx. Currently anonymous namespaces get random names so successive builds of the compiler have different binaries when built with C++. The patch marked anonymous namespaces so they could be compared by pointer instead of string allowing removal of the random naming. Obviously a different strategy is needed. I missed the ABI breakage when testing. Sorry for the aggravation. Jerry
