Hi,

I am using BOOST to do math and have not been able to get the
"findroot_demo.cpp" example of root finding to work. There seem to be a
reference to rint(), which is not implemented in the C++ library for
windows. How can I solve this - my understanding of BOOST is that it is
cross-platform?

Thanks in advance.
