To: gcc-bugs
This is a recent regression that breaks compiling boost:
-------------------
template <bool> struct S {};
typedef S<false> B;
struct D1 : B {};
struct D2 : B {};
--------------------
g/x> /home/bangerth/bin/gcc-4.0-pre/bin/c++ -c x.cc
x.cc:6: error: duplicate base type `B' invalid
Needless to say that the error message is completely bogus.
