If I understand correctly, symbols that are defined in an anonymous
namespace can't be used from outside the compilation unit, regardless of
their linkage. If that's correct, then generating a UUID every time a
file is compiled, and using that for the namespace name (suitably
protected with leading underscores), would solve the problems, wouldn't
it? It doesn't matter if a later compile of the same file with the same
compiler options used a different namespace name, because things like
teimpate instantiations based on the anonymous-namespace types would be
regenerated anyway.
