//JODO REMOVE THIS TESTCASE

#define BOOST_TEST_MODULE icl::fix_include_after_thread unit test
#include <boost/config.hpp>
#include <boost/test/unit_test.hpp>

//Problem: If <boost/thread.hpp> is included before this
//example code, it influences compilation: Code that has
//compiled well, produces a syntax error error C2059 under 
//msvc-9/10. This can be fixed by enclosing subexpressions
//like some_attribute<Type>::value in parentheses
//  ->(some_attribute<Type>::value)
//The problem does not occur for gcc compilers.

// #include <boost/thread.hpp> MEMO: The problem occured when using thread.hpp
#include <boost/bind.hpp>    // but is also triggered from bind.hpp alone
    // while the cause of it is an error in the msvc-7.1 to 10.0 compilers.
    // A minimal example is provided by test case 'cmp_msvc_value_born_error'

//--- included code ---------------------------------------
