#1 Visual C++ 6.0 compilation

[Anonymous]

Dear Nicola Santi,

Thank you for the excellent Eternity framework.
It work greate with Borland compiler, but I have found a problem with Microsoft Visual C++ 6.0 compiler. I was not be able to compile examples.

persist_xml.hpp line 67
'void' function returning a value:

void close()
{
return done();
}

There are some problems with templates.

Best wishes,
Alexei Nikitin.

I see the same errors in algorithms.hpp in Visual C++ .NET
2001. I have not tried 2003.

I was able to "fix" it by a few modifications to algorithm.hpp.
It does change the usage a small amount too, and it isn't
working for associations either (yet).

The problem is that Visual C++ .NET 2001 doesn't support
templated methods within template classes. It chokes on the
template <typename T> template<typename U>
class::method syntax.

E-mail me at jkint@users.sourceforge.net for the modified
files and explanation.
