Hi, There have been various discussions on here about the problems caused by _SECURE_SCL, but I haven't seen any concrete plans for changes to boost build to handle it. At a minimum the build system should be changed to enable those users wanting _SECURE_SCL=0 to do so easily - ideally by providing an argument to bjam. Is someone working on this? Thanks.
