 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.
