Hello,

When I build 1.38.0 with bjam in release configuration, is it built with * _SECURE_SCL*=*0*?

I think adding -n option to bjam will tell you the exact command lines, so you can check yourself.

If not, how exactly can I enforce it?

bjam define=_SECURE_SCL=0 See http://www.boost.org/boost-build2/doc/html/bbv2/advanced/invocation.html - Volodya
