   Oh, ok. I thought it would be a question of fixing some gcc
configuration in my system -- but I should rather be looking at it from
the other side then; that the build system needs to take NetBSD into
account? Hmm... More work. :-)

   Anyway, I hard coded the Makefile for NetBSD / pkgsrc (just to try
it), and found that there's something fishy going on with boost on my
NetBSD/amd64 3.0 system.

   When I build the sample application on an NetBSD/i386 3.0 system, it
compiles and runs fine (though compiling takes quite a while, due to
boost). But on my NetBSD/amd64 system, g++ hangs. It consumes 100% CPU,
but just sits there -- apparently doing nothing but stealing time.

   I would like for someone else to try and see is they get similar
results. Is it ok if I attach some code to the mailing lists? (It's not
much; around 2KB). What list would be appropriate for investigating this
problem further?

   Yes, thanks. I'm kind of used to OS/2 where you can make certain
assumptions about the environment. I guess I need to forget about these
assumptions.
