Hi,
 This problem has appeared before on the list but in a different
context.  The following code

 std::vector<int> myvec;
 for_each(myvec, std::cout<<_1<<' ');

 gives the error:

Serializer.h:78: error: reference to ‘_1’ is ambiguous
/home/sandeep/Computing/boost_1_38_0/boost/lambda/core.hpp:69: error:
candidates are: const boost::lambda::placeholder1_type&
boost::lambda::<unnamed>::_1
/home/sandeep/Computing/boost_1_38_0/boost/bind/placeholders.hpp:54:
error:                 boost::arg<1> <unnamed>::_1
Serializer.h:78: error: reference to ‘_1’ is ambiguous

I believe boost/bind is getting included indirectly via some other
library.  I have tried several modification but none seem to work as I
was quite reluctant to post a third mail on the list.

Thanks,
