Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

Fix several memory leaks (TSchemaRuleSet, TClass, TFolder, stress, TStreamerInfo, TFile, TFree)
Introduce a new preprocessor symbol (R__COMPLETE_MEM_TERMINATION) that allows for
better tracking of memory leak. When ROOT is compiled with this symbols is defined,
globally held objects will be deleted at the time of the process termination.
With this symbol defined, some tests (root.exe -b -l -q ; test/stress ;) run under
'valgrind --leak-check=yes' with no memory leak reports (but still a few still
reacheable blocks). However, this does not yet support (i.e. segfault at termination)
the case where TFunctions are created on the 'CINT' stack (and thus fails roottest) and
some uses of CINT functions for fitting ... and probably also fails on Windows.

Mega patch to add support for large files (bigger than 2 GBytes)
----------------------------------------------------------------
==========>NEW VERSION 4.00/00 <===========
Because this new version has a considerable number of changes,
and new important additions by Philippe are scheduled for the coming days
we are starting a new major version 4.
-Support for large files
-Automatic schema evolution for foreign classes
-New data type Double32_t
Large files are currently tested only under Linux with gcc3.2.
Support for other systems will be gradually added in the coming days.
By default under Linux, files are created with the option LARGEFILE.
Note that when creating a Tree, the default maximum size for a Tree
is set to 1.9 GBytes. You can change this default value by calling
TTree::SetMaxTreeSize(Long64_t maxsize)
The implementation of this new feature has required changes in many places.
The files produced by this new version can still be read by old ROOT versions
if their size if smaller than 2 GBytes. And obviously, the new version
can digest old ROOT files.
WARNING: note the following backward incompatibility:
-TSystem::GetPathInfo has a new signature: (also TUnixSystem, TWinNTSystem, etc)
old: GetPathInfo(const char *path, Long_t *id, Long_t *size, Long_t *flags, Long_t *modtime);
new: GetPathInfo(const char *path, Long_t *id, Long64_t *size, Long_t *flags, Long_t *modtime);
-TFile::SysSeek and TFile::SysStat have a new signature (also TNetFile, TWebFile, etc)
old: Int_t SysSeek(Int_t fd, Long_t offset, Int_t whence);
Int_t SysStat(Int_t fd, Long_t *id, Long_t *size, Long_t *flags, Long_t *modtime);
new: Long64_t SysSeek(Int_t fd, Long64_t offset, Int_t whence);
Int_t SysStat(Int_t fd, Long_t *id, Long64_t *size, Long_t *flags, Long_t *modtime);
-TTree::SetMaxTreeSize has a new signature:
old: void TTree::SetMaxTreeSize(Int_t maxsize)
new: void TTree::SetMaxTreeSize(Long64_t maxsize)
All references to Seek_t have been replaced by Long64_t.

Implement all the changes required to process files > 2 GBytes.
Activating this option will imply changing Seek_t to long long.
We hope that Masa will implement the longlong type by default
in the not too distant future in CINT.
The file format remains compatible for files smaller than the
threshold set in TFile::kStartBigFile = 2 GigaBytes.
The changes are the following:
in TFile
========
Remove the enum kBegin, kUnits (not used anymore).
Add new enum kStartBigFile
When creating a new file (in TFile::Init) fBEGIN is now set to 100
bytes instead of 64. TFile::WriteHeader is called assuming that
the file will be smaller than kStartBigFile.
When closing the file, if the file is bigger than kStartBigFile,
a new format is used in WriteHeader using 64 bits to store all
values of type Seek_t and the file version (fVersion) is set
to fVersion+1000000.
All functions like TFile::Map, TFile::Recover have been adapted
to follow the new convention.
in TDirectory
=============
TDirectory::Sizeof has been modified to return 12 bytes in addition
for fSeekDir, fSeekParent and fSeekKeys when writing a directory
in a file bigger than kStartBigFile.
The TDirectory constructor is setting a temporary bit to inform
the function Sizeof that it has to return 12 addtional bytes.
TDirectory::FillBuffer writes fSeekDir, fSeekParent and fSeekKeys
with 64 bits if necessary. The version number of the directory
is set to TDirectory class version + 1000 in this case.
Corresponding changes in TDirectory::ReadBuffer and TDirectory::Streamer.
in TFree
========
TFree::Sizeof has been moved to the implementation file.
Like for TDirectory, the functions FillBuffer and ReadBuffer have been
modified to write fFirst and fLast in 64 bits if necessary.
When writing in 64 bits mode, the TFree version is incremented by 1000.
in TKey and TBasket
===================
Same changesas in TDirectory in teh functions FillBuffer, ReadBuffer
and Streamer. The TKey version number is incremented by 1000
when writing in 64 bits mode.
