From Andrew Savchenko:
ROOT can not be compiled with gcc-4.3.
Some ROOT source files doesn't contain required #include directives,
for example, they use strlen(), but #include <string.h> is missed or
malloc() is used and #include <stdlib.h> is missed.
Earlier versions of gcc allowed some headers to be included implicitly,
but issued a warning (-Wimplicit-function-declaration). Newer one,
gcc-4.3 denies such silly behaviour: all required headers must be explicitly
included.
Attached patch fixes this. Also it fixes another issue, which disallows
ROOT to compile under gcc-4.3: C functions don't belong to namespace std,
so expressions like std::memcpy() are no longer valid and plain memcpy()
should be used instead.

In the Streamer functions replace the lines like
TPad::Class()->ReadBuffer(b, this, v, R__s, R__c);
TPad::Class()->WriteBuffer(b,this);
by
b.ReadClassBuffer(TPad::Class(), this, v, R__s, R__c);
b.WriteClassBuffer(TPad::Class(),this);

-Add include "TROOT.h" in all implementation files that were assuming
that TROOT was included via TClass.h
-In TClass.h:
--Remove the include of TROOT.h
--add the following static member
static IdMap_t *fgIdMap; //Map from typeid to TClass pointer
--add the following functions:
static void AddClass(TClass *cl);
static void RemoveClass(TClass *cl);
--Replace the inline definitions of GetClass functions by
template <typename T> TClass* GetClass( T** /* dummy */) { return GetClass((T*)0); }
template <typename T> TClass* GetClass(const T** /* dummy */) { return GetClass((T*)0); }
-In TClass.cxx:
--Instead of forwarding the calls to gROOT->GetClass, move the code
originally in TROOT in the TClass::GetClass functions
--Move class TMapTypeToTClass from TROOT to TClass.

Extend the functionality of the Print function, giving the possibility
to specify the format to print the matrix.
// By default the format "%11.4g" is used to print one element.
// One can specify an alternative format with eg
// option ="f= %6.2f "

From Eddy Offermann:
Previously, the matrix package contained a large amount of ASSERT
statements which are a nuisance for programs analyzing a series of
independent events like in high-energy physics .
Assert's were issued when for instance a division by zero was requested
or a matrix was invalid . Most algorithms made matrices/vectors invalid
after an error occured in an operation , like inversion of a singular matrix .
Unfortunately, not all assert's were accompanied by error messages .
This situation has been completely overhauled :
- All error conditions in the algorithms are now accompanied by error
messages .
- In all algorithms it is still asserted that vectors/matrices are
valid BUT only in very few cases is a matrix/vector made invalid :
for instance if memory is allocated with incorrect parameters .
- In case of division by zero, the division is skipped . In case of a
singular matrix, the inversion routine returns the original matrix .
In the past the result of an inversion could be checked through the
value of the returned determinant or checking whether the inverted matrix
was valid .
Since from now on, we never make the matrix invalid in this operation, the
latter check will not indicate a singular matrix anymore .
The decompostion classes TDecomp... have a backward-compatible
change in the interface which makes detection of singularity easier :
old interface :
void Invert (TMatrixD &inv);
TMatrixD Invert ();
new interface :
Bool_t Invert (TMatrixD &inv);
TMatrixD Invert (Bool_t &status);
TMatrixD Invert () { Bool_t status; return Invert(status);
}
The returned status is kFALSE in case of singularity .
The old situation is easily reproduced by setting the ROOT variable
gErrorAbortLevel to kError . This cause an exception when there is an error
message (Error...) ., In the past the matrix would be made invalid which
would cause the next operation to throw an exception .

Change the TError.h macros:
Assert -> R__ASSERT
Check -> R__CHECK
Change the TCollection.h macro:
ForEach -> R__FOR_EACH
This to avoid potential problems due too trivial macro names.
The old macros will be removed in the next release. Currently
they will print out warning messages with the advice to move
to the new macro names.

Reduce direct dependencies on TClass.h, TROOT.h and TStreamerInfo.h.
Warning: This means that some file that relied on the indirect
inclusion of these header file might now fail to compile with
an error message mention that gROOT is no known or that TClass,
TROOT or TStreamerInfo is incompletely defined. Simply add the
proper include directive.

From Eddy:
a patch that will hopefully resolve the Solaris issue .
From the error messages I deduce that the compiler does not like to
instantiate
a default templated argument in the function header . Therefore, I
replaced the default
value by the value 0.0 (which is an unusual value , the user would use
here "==")
and check in the routine and replace it with the appropriate epsilon.
