Test case fixed using forward declarations

Thank you for your help. I think I now have a better understanding of what is
going on. As far as GCC is concerned the overriding visit_each template
function dealing with MyData does not exist when it makes its decision
regarding visit_each(v, data, 0); call.

I am attaching fixed (working with 4.1) text case that is more representative
of the boost structure (to the best of my understanding). Also, I will be using
it as a base for a follow up issue I ran into.

I am also including couple of relevant links for better context to this issue
for anyone else who might stumble on this entry:

Two Phase looks ups and GCC:

http://gcc.gnu.org/gcc-3.4/changes.html
http://gcc.gnu.org/onlinedocs/gcc/Name-lookup.html
http://developer.apple.com/releasenotes/DeveloperTools/RN-GCC4/index.html

IMHO, the changes are mentioned as early as gcc 3.4 but they did not seem to
fully kick in until gcc 4.x.

Related boost email and change that I found:
