tags 356241 +patch thanks In standard C++, friend functions that are only declared inside a class can only be found by argument-dependent lookup (and can only be defined inline, though it's not a syntax error to fail to do so!)
The attached patch fixes the compilation errors.
The warnings about "has virtual functions but non-virtual destructor"
appear to be bogus since the destructors in question are protected.
These should be suppressed using the "-Wno-non-virtual-dtor" option.
There are other remaining warnings which should be investigated.
Ben.
