Dictionary G__%.o: G__%.cxx rules now in main Makefile instead of Module.mk's
=> changes in Module.mk.

First Module.mk's included, then Makefile.precomp - we need ALLHDRS defined

Split $(PCHEXTRAOBJ) and $(PCHFILE) rules - fixes clash with make -j2

Define CINTCXXFLAGS:= - otherwise they will contain PCHCXXFLAGS via
their definition as a copy of CXXFLAGS.

MSVC: prevent LNK4206 linker warning (-Yl...)

handle in a consistent way the new rootcint options -cint (default),
-reflex and -gccxml. The type of dictionary to be used can be specified
like: ./configure --with-dicttype=reflex. Notice that this option is
there only for the developers working on the migration to the new
dictionary system.

in case we have gmake >= 3.80 we can use the new | (order) syntax where
all dependencies after the | are required to be there but not trigger
execution of the rule. This should greatly enhance the build experience
on Win32 and AIX (platforms that need the EXPLICITLINK option).

      * New Debian and RedHat rpm packaging scripts.
      * Added a description to `build/package/debian/README.Debian' on
        how to add a new package.   It's not that complicated so it
        should be a simple thing to add a new package, even for some
        with little or no experience with RPMs or DEBs.
      * When searching for the Oracle client libraries, I added the
        directories `/usr/lib/oracle/*/client/lib' and
        `/usr/include/oracle/*/client' - as these are the paths that the
        RPMs install into.
      * I added the packages `root-plugin-krb5' and
        `root-plugin-oracle'.
      * The library `libXMLIO' is in `libroot'.
      * The package `root-plugin-xml' contains the XML parser.
      * I fixed an cosmetic error in `build/misc/root.m4'.  The
        definition of `ROOT_PATH' should be quoted, otherwise aclocal
        will complain.
      * In the top-level `Makefile' I pass an additional argument to
        `makecintdlls' - namely `$(ROOTCINTTMP)'.  In `makecintdlls' I
        use that argument to make the various dictionaries for
        `lib...Dict.so'.   Originally, the script used plain `rootcint'.
        However, as `rootcint' may not be in the path yet, or the one in
        the path may be old, this failed.  Hence, I use what we know is
        there - namely the newly build `rootcint_tmp'.  BTW, what are
        these shared libraries, and where do they belong?  I guess they
        are specific to ROOT, and not used by plain `CINT'.  For now, I
        put them in `libroot'.
      *  Made the two `virtual' packages `root-db-client' - provided the
        DB plugins, and `root-fitter' provided by `root-plugin-minuit'
        and `root-plugin-fumili'.  Note, the virtual package
        `root-file-server' provided by `root-rootd' and `root-xrootd'
        already existed in the previous patch.
      * Note, I added the directory `build/package/debian/po' which is
        for translations of DebConf templates.  DebConf is Debians very
        advanced package configuration interface.   It presents the user
        with a set of questions in some sort of `GUI' based on how much
        the user would like to change.  These `dialogs' can be
        translated quite easily.  As an example, I translated the
        questions used by the `ttf-root-installer' package into Danish.
        I'm sure someone can translate them into German, French,
        Italien, Spanish, and so on.

----------------------------------------------------------------

  ==========>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.

calling ReOpen().

files via the Chirp protocol (http://www.cs.wisc.edu/condor/chirp).
This works especially nicely with the Condor job manager
(http://www.cs.wisc.edu/condor) that we and many others are using to run
CMS event simulations.  The patch to v3.03.0 is attached if you would
like to include this in your distribution.  It touches nothing outside
of the new module other than adding config entries.

Normally, remote system calls by jobs in Condor are handled
transparently as though the job were executing on the original submit
machine.  (This has been very useful to us in Wisconsin, because we use
a large pool of execution machines that are not specially configured and
which therefore do not share a filesystem with our submission machines.)
However, this requires relinking the application with some special
libraries which are currently not compatible with the new multithreaded
CMS software.  By adding a Chirp plugin to ROOT, we are able to
selectively enable remote access wherever we need it, simply by
prepending "chirp:" to the file names (assuming TFile:Open() is used, of
course).  No additional daemons need to be installed or configured
unless we want to serve up the files from a machine other than the
submit machine. Code contributed by Dan Bradley.
