We could take advantage of the fact that the C++ Standard provides for this:

    #if __cplusplus >= 199711L
    namespace std {
    #endif

GCC 2.95 wouldn't see the namespace that way.

Currently we're still (nonconformingly) defining __cplusplus to be 1
rather than the value defined by ISO.  We tried to fix this once before,
but because Solaris already /does/ #if's like this one, we suddenly started
picking up system headers that we weren't before.  Some work on this has
already been done.
