Dear group members! I am currently using the interval library and the following linker errors pop up: error LNK2028: unresolved token (0A000596) "extern "C" double __cdecl rint(double)" (?rint@@$$J0YANN@Z) referenced in function "public: static double __cdecl boost::numeric::interval_lib::detail::x86_rounding::to_int(double const &)" (?to_int@x86_rounding@detail@interval_lib@numeric@boost@@$$FSANABN@Z) Internal.obj Docs.Evaluation error LNK2019: unresolved external symbol "extern "C" double __cdecl rint(double)" (?rint@@$$J0YANN@Z) referenced in function "public: static double __cdecl boost::numeric::interval_lib::detail::x86_rounding::to_int(double const &)" (?to_int@x86_rounding@detail@interval_lib@numeric@boost@@$$FSANABN@Z) Internal.obj Docs.Evaluation rint does not show up in the MSDN documentation. This seems to be another example of Microsofts C99 compliance problems if I am not mistaken. I found a bug in the bug-database (#446: Bugs: MSVC support (closed: Wont Fix)) but when I try to view the bugreport all I get is a "Trac detected an internal error: TypeError: a float is required". Guillaume Melquiond seems to have posted a workaround in https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1246358&group_id=7586 but I cannot view this either, because this artifact is private and can be viewed only be groupmembers of a certain group (no idea which one). Would it not be a solution to simply add an rint implementation to the interval library?
