This is primarily the problem: To make MSVC 6.0 compile a program
using Boost.MultiIndex you've got to observe some stricter rules than
in the normal case. Please read the section on MSVC 6.0 at

http://boost.org/libs/multi_index/doc/compiler_specifics.html#msvc_60

Problem #1: MSVC 6.0 does not support the "index" nested typedef.
Instead, write

        typedef index<employee_set,ssnumber>::type employee_set_by_ssn;

>         employee_set_by_ssn& ssn_index=es.get<2>();

Problem #2: MSVC 6.0 does not support the get member function, use the
global
version instead:

        employee_set_by_ssn& ssn_index=get<2>(es);

With these changes, and also tweaking /Zm and /ZI (as explained in the
aforementioned section), your program compiles. Bare in mind that your
compiler is very old and broken and making Boost.MultiIndex work for it
can be quite a challenge, although it is doable. Good luck with your
project,
