upgrade to Pythia8 >= 8180. Previous versions don't compile with latest clang.
Fix http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=17054&p=73075#p73075
Rename the c++11 option as cxx11 feature. Needed for root-config.in
Make Bagged Sample use for AdaBoost and GradBoost being called by the same option named *UseBaggedBoost* instead of *UseBaggedGrad* and replace the *random subsample* by a true resampled(bagged) sample
adapt also the example files to the new option names
force overwriting of symbolic links to *rootmap* such that one can also switch between different TMVA verions
Fix typos
Fix a potential crash when there is a line longer than the terminal width (taking two or more lines to display) in the history (using up arrow key) in a ROOT session while the terminal's buffer is full
Make a new templates inline version of TMath::Nint which is two-times fast
Thanks to S. Wenzel ( see ROOT-5290 )
Fix an if condition in TMath::Quantile taking into account numerical errors
(this fixes a wrong result obtained in 32 bit arch , with extended precision)
extend interface of FlexibleInterpVar to change nominal/high/low values
Two new characters #minus and #plus typographically better than the standard "-" and "+"
fix SumW2Error correction

two oversights are now fixed:
1. TMatrixDSym is not really symmetric, i.e. changing M(i, j) does not
   change M(j, i), so add a for loop which does that after inversion
   (since the inversion routine only fills the diagonal and below)
2. the new matrix inversion with Cholesky decomposition was not used for
   the old minimiser

implement analytical integrals of RooHistPdf over subranges

RooHistPdf provides analytical integrals, but the result ignores the
range parameter completely. This patch updates RooHistPdf and the
underlying RooDataHist class to provide this functionality.

fix initialisation hazard in RooDataHist

previous patch to RooDataHist could leave the new _binbounds array
uninitialised before it was used, so we check explicitly

RooAbsReal: recognize RooFit::Minimizer in chi2FitTo, pass on full RooFit::Optimize setting

sanitise RooAbsArg leafNodeServerList, branchNodeServerList and treeNodeServerList

joining the sets returned by the former two methods should form the set
returned by the latter

otherwise, this implies that we have nodes in the expression tree which
are neither leaf nor branch nodes

mention pythia8 needs to be >= 8180.
port of v5-34-00-patches to support libc++.

This port is needed as OS X 10.9 will support natively only libc++
as C++ run-time library. Extra complication is the needed hand tuning of the
changed libc++ STL and iostream implementation for CINT. Some CINT STL
interfaces still need to be fixed before this port is operational.
Compile using --enable-cxx11 (which automatically turns on --enable-libcxx).
