12179,Including boost/optional/optional_fwd.hpp without first including boost/config.hpp doesn't compile.,c.d.glover@…,Fernando Cacciola,"This code does not compile;

#include <boost/optional/optional_fwd.hpp>

int main()
{
    return 0;
}

It seems this is because optional_fwd.hpp tries to only depend on boost/config/suffix.hpp, but this file itself depends on other config macros that need to be included first.

I have been able to workaround this issue by including boost/config.hpp before optional_fwd.hpp",Bugs,closed,Boost 1.62.0,optional,Boost 1.61.0,Problem,fixed,,
