Thank you for the bug report. Unless there is a typo, this
constructor appears to always require a copy of "gen"?
 foo(const base_generator_type gen)
If you want to avoid binding to the Generator& constructor
and use the copy constructor instead, you should make sure
to convert "gen" to an rvalue (e.g., by using a
static_cast<const base_generator_type>(...)) before
initializing m_gen. (untested idea).

Independent of the boost.random implications, it worries me
that two compilers choose two different overloads. That
Should Not Happen (tm). Could you try to come up with a
short example not depending on any libraries that shows the
difference so that Metrowerks and GCC can have a look at it
who is right? If you do it in the next 2 days, I can discuss
it with the compiler authors here at the ISO C++ meeting.
