In order to compile with older compilers the variable SPIRIT_ROOT has to be
defined and point to the root where spirit is installed.

So the build jamfile would have to be modified so that that the modules for
XML are build if and only if:

a) If the compiler is an older compiler
b) && SPIRIT_ROOT is defined to something not null
c) || the compiler is a newer compiler.

I think the build jamfile could altered to do this.  I spent a little time
at it but didn't immediately see how to do it.  But I think it should be
possible.  Its probably trivial for a BJAM guru - so feel free anyone.  Also
it would be nice if it echoed a comment indicating that its skipping the XML
components for lack of SPIRIT_ROOT.
