A new operator [] const.
its purpose is the same as the At(Int_t i) does.
But with it you don't have to care whether the method you
are using is const or not: on the right hand side of an
equation always the operator [](Int_t i) can be used for
datamember-TArray's!

The function in TNamed::Hash is not convenient for TKey in case many keys
have the name but different cycles.

The test for "insideness" in TBox::DistancetoPrimitive in the case of
a filled TBox misses the TBox's very edge.  This causes 1 pixel
wide/tall TBoxes to be invisible to pointer interactions.

An array of objects is written to a file but the TRefs
referencing these objects are not written to the file.
In a next session, these objects are read in memory
and new TRefs point to these objects and are written
to a separate file. In a third session both files
are connected.
To get this scenario working, one must use a dummy TRef
set to all objects that can be referenced in the next session.

"We had problems compiling root with CC6.2 when applying the -D_REENTRANT
 flag, see forwarded mail below from a collegue of mine, Harray Felder.
 It does the minimal change I found necessary to be able to use the _REENTRANT
  define in our compilation of root. (This define is used to cause the system includes
  to generate some function calls instead of macros so that libraries
  can potentially be used in a multithreaded executable, although in a single-threaded
  manner. We are now setting this flag everywhere so that we can incorporate some
  libraries into java programs, which are inherently multithreaded.)"
