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

  23 #include <boost/bind.hpp>    // but is also triggered from bind.hpp alone
  24     // while the cause of it is an error in the msvc-7.1 to 10.0 compilers.
