This problem still exists with the 2005-03-11 distribution tarball.

I have tried newer versions of the compiler, with identical results.

Sun's documentation implies that they do not consider this behaviour a bug;
see http://www.sun.com/software/sundev/suncc/faqs/cpp.xml#q17 .
Their suggested solution (patch below) appears to work (compile-time test 
only) both with their compiler and with g++ (I tried 2.95 and 3.3.5).

I am not enough of a C++ language lawyer for my opinion to carry much weight,
but I suspect that they are right and the unpatched BasicHashTable.hh is not
standard-conforming.
