cannot use both students_t.hpp and unit_test.hpp

[Martin Ankerl <martin.ankerl@…>]

This code does not compile:

#include <boost/test/included/unit_test.hpp>
#include <boost/math/distributions/students_t.hpp>

static void log_test()
{
  boost::math::students_t dist(0.5);
  double p = boost::math::cdf(dist, 1.0);
}

I get this error message:

d:\dev\trunk\lib_boost\inc\boost\math\special_functions\log1p.hpp(407) : error C2882: 'log' : illegal use of namespace identifier in expression

it can be fixed by changing the offending line

return log(u)*(x/(u-1.0));

into

return ::log(u)*(x/(u-1.0));

but I am not sure if this is a good fix. I have tried this on an older version we are working with, and on the current svn trunk.
