Comment (by johnmaddock):

 There are several points here:

 1) The compiler is entitled to reject PrintTest if std::endl and
 std::distance have not been declared ''even if the function is never
 instantiated''.  GCC and Clang are examples that will do this.
 2) iostream and associated headers are part of the standard, it's not
 unreasonable to reply on them.
 3) The only Math lib header mentioned above is only ever used when
 generating new numeric constants so should never be an issue in practice.

 There is an include of <iostream> in boost/math/tools/precision.hpp which
 isn't needed which I'll remove.

 And finally, please file one bug report per library.
