Yes, I'm aware of this danger. But since my system (Fedora Core 5)
contains boost libraries (release 1.33, I think) all without the 'mt' tag,
and as I thought at least some would be compiled with multithread
support, I concluded something was wrong.
(Writing these lines I realize I'm still not sure I understand what
'multithread support' actually means in this context.)

Thanks for the clarification !

Ah, I see. But that shouldn't be a reason not to document it somewhere
on boost.org, should it ? ;-)

Thanks,
