One of Boosts major concerns is about portability, so they work fine
on MacOSX, and from what I hear, osx has a binary of boost with it as
well, so it should provide no problem. I'm mainly targetting nct, who
tries to keep an eye on dependancies. As well, a full fixed width
integer class is not simple, especially when it comes to devision and
multiplication, where as multipling to decimals shrinks the result,
and deviding by a decimal increases the result, quite the opposite of
what the default integers do, which is why I so desperately want to be
allowed to use Boost, which provides a full rational number library
that would solve my problems. There are also a variety of otheer boost
libraries which would come in very handy, and adding a dependancy for
a single Boost library is dumb as boost generally comes (on all posix
systems and their windows binaries) as one big collection rather than
individual libraries.
