math float_advance causes link error for itrunc - missing include in boost/math/special_functions.next.hpp

[Paul A. Bristow]

boost/math/special_functions/next.hpp

doesn't include

boost/math/special_functions/trunc.hpp

and hence I get linker errors when only including the former and using boost::math::float_advance:

main.cpp

---

#include <boost/math/special_functions/next.hpp> including this prevents the linker error #include <boost/math/special_functions/trunc.hpp>

int main(int argc, char argv) {

double x = boost::math::float_advance(1.0,1); return 0;

} reported by Jeffrey Hellrung and confirmed.

Fix is to add #include trunc.hpp to next.hpp

But this should have been detected?
