Can we uncomment those operator-> implementations at least for
TQPtrList and TQValueList iterators? It 's a real pain to use
iterators without them.

Comments in qptrlist.h says there were some malfunctions in MSVC and
Sun compilers but I suppose these information refers to old versions.
All in all I don't think that tqt may be build by them without any
other problems.

I can prepare the patch. Am I supposed to prepare it for qt or tqt?
