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.

Funny enough: GUI can give me '*' as a font's foundry, but if I RETURN '*' as a foundry,
it crashes - parses this XLFD, sets foundry to 0 and later use strcasecmp on this pointer.
1. 'Fix' TGFontPool not to use 0 pointers,
2. return fake foundry.

Skip some characters causing problems with newer versions of libfreetype. These are extended ASCII characters and not used in the GUI anyway.
This should solve the bug #58945: Fatal crash when enabling Xft (font smoothing) on some newer distributions

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so expressions like std::memcpy() are no longer valid and plain memcpy()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.

From Valeriy Onuchin:
Changes in font handling connected with html widget development and allows to find the best matching font specified by family, point size, weight, slant. They include:
- new structure describing font attributes
struct FontAttributes_t {
const char *fFamily; // Font family. The most important field.
Int_t fPointsize; // Pointsize of font, 0 for default size,
// or negative number meaning pixel size.
Int_t fWeight; // Weight flag
Int_t fSlant; // Slant flag
Int_t fUnderline; // Non-zero for underline font.
Int_t fOverstrike; // Non-zero for overstrike font.
};
- new class TGTextLayout is used to keep track of string
measurement information.
- new TGFont methods (see descriptions in the source):
Int_t TextWidth(const char *string, Int_t numChars = -1) const;
Int_t XTextWidth(const char *string, Int_t numChars = -1) const;
Int_t TextHeight() const { return fFM.fLinespace; }
void UnderlineChars(Drawable_t dst, GContext_t gc,
const char *string, Int_t x, Int_t y,
Int_t firstChar, Int_t lastChar) const;
TGTextLayout *ComputeTextLayout(const char *string, Int_t numChars,
Int_t wrapLength, Int_t justify,
Int_t flags, UInt_t *width,
UInt_t *height) const;
Int_t MeasureChars(const char *source, Int_t numChars, Int_t maxLength,
Int_t flags, Int_t *length) const;
void DrawCharsExp(Drawable_t dst, GContext_t gc, const char *source,
Int_t numChars, Int_t x, Int_t y) const;
void DrawChars(Drawable_t dst, GContext_t gc, const char *source,
Int_t numChars, Int_t x, Int_t y) const;

from Axel:
Change the signature of SavePrimitive from
void SavePrimitive(ofstream &out, Option_t *option);
to
void SavePrimitive(ostream &out, Option_t *option = "");
With this change one can do, eg
myhist.SavePrimitive(std::cout);
WARNING: do rm -f tree/src/*.o

From valeriy Onuchine:
- TImage, TASImage
o Change return type of Vectorize method from "void" to "Double_t*".
o Implement FromWindow method under X11. This method allows to
create "snapshot image" from any ROOT window or frame.
- config/Makefile.depend
Add dependency of libGuiBld lib on libGraf.
GuiBuilder uses internally TImage/TASImage class.
- GX11Gui.cxx
X11 error handler was slightly modified.
Many X11 errors lead to freezing X11 server and
did not allow debugging.
To prevent freezing, a "forced seg.violation" was added
to the error handler.
The usage of the new "feature" is the following:
0. run "gdb root.exe"
1. set "gDebug = (int)gVirtualX" - that activates the new error handling.
2. run application which has X11 errors.
On X11 error the application was stopped by the "forced seg.violation".
3. "gdb>bt" - backtrace the problem.
!!! A big list of changes in libGui initiated by gui builder development !!!
- TGButton.h, TGButton.cxx
TGButton class:
o SetDown methods removed from context menu.
o SetEnabled method of context menu changed to TOGGLE.
Setting fWidgetFlags was added.
- TGTextButton class
o GetNormGC(), GetFontStruct() methods are introduced.
o SetFont removed from context menu.
o ChangeText(const char *title) was introduced and added to context menu.
o fixed an error in SetFont method which set font globally instead of
locally.
o SavePrimitive - save text justification
- TGPictureButton
o added getter method GetDisabledPicture()
- TGCanvas
o added to GuiBuilder widgets palette.
- TGColorDialog
o new methods:
- TGColorPalette *GetPalette(),

- void SetCurrentColor(Pixel_t col)
o new signal:
- void ColorSelected(Pixel_t)
o new parameter added to contructor "Bool_t wait".
If "wait" is kTRUE, "gClient->WaitForUnmap" is called internally
(normal/old usage). If "wait" is kFALSE - "gClient->WaitForUnmap"
should be called by user.
o few "usefull" colors added to "custom" palette.
- TGColorSelect
o added to GuiBuilder widgets palette.
- TGComboBox
o new methods:
- SortByName - allows to sort combobox entries by names.

now it works on X11 also.
It allows to select any font available on the system.
o new parameter added to contructor "Bool_t wait".
If "wait" is kTRUE, "gClient->WaitForUnmap" is called internally
(normal/old usage). If "wait" is kFALSE - "gClient->WaitForUnmap"
should be called by user.
o new methods:
void SetFont(TGFont *font);
void SetColor(Pixel_t color);
void SetAlign(Int_t align);
void EnableAlign(Bool_t on = kTRUE);
void UpdateStyleSize(const char *family);
o new signals:
- FontSelected(char *font)
- AlignSelected(Int_t a)
- ColorSelected(Pixel_t c)

From Ilka:
Any ROOT GUI can now be saved as a macro. Executing this macro brings back
the current GUI (minus the action handling). This very important development
allows to get easily the source for any GUI, which can then be inspected or
used to create other GUI's. Also this will allow a GUI builder to save and
restore GUI's.
To save the source of a GUI use the methods TGMainFrame::SaveSource() or
TGTransientFrame::SaveSource(), where the latter saves the source for dialogs.
To trigger the saving of any GUI just use ctrl-s.

major changes in the resource management of the GUI classes. Introduced the
new class TGResourcePool which loads and keeps track of the 3 main resource
pools: fonts, picture and graphics contexts. Fonts are now handled via the
new TGFont class (and TGFontPool). In the past the loading of these resources
was done in TGClient and required all GUI classes to have TGClient as friend
to have their global statics initialized by TGClient. Adding a new widget
required TGClient.cxx to be changed too. This was obviously not good.
In addition it is now possible to find the full definition of the original
resource back based on a resource handle (GContext_t or FontStruct_t yielding
a TGGC or TGFont) which is needed for the SavePrimitive() functionality.
The resource pool can be found via TGClient (e.g. gClient->GetResourcePool()).
To see all active graphics contexts, fonts and pictures do:
gClient->GetResourcePool()->GetGCPool()->Print()
gClient->GetResourcePool()->GetFontPool()->Print()
gClient->GetResourcePool()->GetPicturePool()->Print()
For more examples see the widget source code.
These changes are largely backward compatible except maybe for some low
level 3rd party widgets that use some TGFrame internals. In these cases
the following sed command will patch the code:
sed -e "s/fgBlackGC()/GetBlackGC()()/g" \
-e "s/fgWhiteGC()/GetWhiteGC()()/g" \
-e "s/fgHilightGC()/GetHilightGC()()/g" \
-e "s/fgShadowGC()/GetShadowGC()()/g" \
-e "s/fgBckgndGC()/GetBckgndGC()()/g" \
