This is a request for anyone who is willing and able to help finish

just don't have the time to dedicate to this library to come

is that's meeting). While most of the b

No compile-time error, but a run-time error may occur if multiple
inheritance is used. There is basically nothing we can do in this
situation:

Definitely read ALL of the documentation. after building bjam and jam,
Here are two little classes that could be useful to create aligned types

Well what do you know...
The "order_2_accumulator" class on that page looks just like my "stats"
class. I threw in min and max and have more functions, but otherwise
it's the same.

Hi all,
I have a small family of statistics classes which I have used from time

Here's an example of it's use:

myStats.add(i);
}

I'm newish to C++ and very new to boost.
I've just tried to build the object library for regex

on bcb5, got no errors at that stage, but when I try to compile
my app within the Builder IDE I get a fatal linker error:

I would rather that BOOST_HAS_LONG_LONG was just not defined in the first
place when EDG is in strict mode - any ideas?

Looks like testing for _POSIX2_VERSION would be another option - BTW I'm
tempted to suggest that we add a config macro and tests for this, that way
the configure script will pick this up: BOOST_HAS_SIGACTION maybe?

Maybe, but all I did was invoke the bjam to build everything - and BTW these
linker errors do no

Encapsulating algorithms with a _new_ namespace, and later injecting it into
