Milestone:  To Be Determined  |  Component:  optional

 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
