Dear all, Trying the Vector example at the Proto documentation: http://boost.org/doc/libs/1_45_0/doc/html/proto/users_guide.html#boost_proto... under Boost 1.42 and GCC 4.5.1 (MinGW32, WinXP, SP3), I get the error message in the PS. Any ideas why this is happening? How would I solve the problem? (BTW, I have already tried the Boost 1.42 version of this example as well.)
