[boost] [test] compile error on floating point comparison

The last test results on msvc (RudbekAssociates, as well as huber-V2), have a failure in math library that seems to be caused by Boost.Test. See: http://tinyurl.com/hon2m Seems like "max" and "min" are defined as macros. Per max/min guidelines (http://boost.org/more/lib_guide.htm), I've fixed this with attached patch, and comitted it as obvious. Hope this will fix the issue. - Volodya
