Vadim--It surprises me that this was necessary
http://cvs.savannah.nongnu.org/viewcvs/lmi/lmi/illustration_document.hpp?rev=1.5
because of C++98 3.4.4/3, which gives the example
friend struct Glob; // OK: Refers to (as yet) undeclared Glob
but if gcc-4 rejects it then we need to make this harmless change.
Did you not encounter similar problems with, say,
class XmlNotebook [...]
{
friend class mvc_test;
? There are other instances of this same usage, too.
