DWF Toolkit 7.7 compilation failure on GCC 4.7 and above

[jng]

Building trunk with freshly merged DWF Toolkit 7.7 on Ubuntu 14.04 64-bit produces compilation errors like this

../../../dwfcore/Vector.h:591:41: error: '_tEquals' was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]
             if (_tEquals( oValue, *iter ))

                                         ^
../../../dwfcore/Vector.h:591:41: note: declarations in dependent base 'DWFCore::DWFVector<DWFToolkit::DWFClass*, DWFCore::tDWFCompareLess<DWFToolkit::DWFClass*>, DWFCore::tDWFCompareEqual<DWFToolkit::DWFClass*> >' are not found by unqualified lookup
../../../dwfcore/Vector.h:591:41: note: use 'this->_tEquals' instead

This is due to name lookup changes introduced in GCC 4.7

The easiest solution would be to apply the -fpermissive compiler flag to convert these errors to warnings.

The proper fix, would be to find and replace all instances of _tEquals with this->_tEquals as suggested by the compiler error message
