I've also had problems compiling hurd code using g++.
In addition to what Thomas has described, the ports library is unusable
with C++ because struct port_info has a member named "class".
Also, the initializer syntax used in /usr/include/refcount.h is unusable
with g++. For example:
209 const union _references op =
210 { .references = { .weak = ~0U, .hard = 1} };
generates a compiler error:
sorry, unimplemented: non-trivial designated initializers not supported
To reproduce both problems, just create a file containing the line #include
<hurd/ports.h> and try to compile it with g++. It doesn't matter if you
put it inside an extern "C" block, either.
