include/cppunit/Portability.h: moved OStringStream alias definition to
Portability/Stream.h. User need to define EVC4 to indicate that
config-evc4.h should be used. (how to we detect this automatically ?).
Notes that this means it might be needed to add #include <string> to some
headers since its no longer included by Portability.h.

* include/cppunit/Portability/Stream.h: define alias OStringStream, stdCOut(),
and OFileStream. If CPPUNIT_NO_STREAM is defined (evc4 config), then provides
our own implementation (based on sprintf and fwrite).

* include/cppunit/config/config-evc4.h: config file for embedded visual c++ 4.
Still need to detect for this platform in Portability.h (currently relying on
EVC4 being defined...)

* *.[cpp/h]: most source files have been impacted with the following change:
#include <iostream> -> #include <cppunit/Portability/Stream.h>
std::ostream -> CPPUNIT_NS::OStream
std::ofstream -> CPPUNIT_NS::OFileStream
std::cout -> CPPUNIT_NS::stdCOut()
std::endl -> "\n"
Also, code using std::cin as been defined out if CPPUNIT_NO_STREAM was defined.
The exact list of impact files can be obtain in CVS using tags:
TG_CPPUNIT_NO_STREAM_BEFORE & TG_CPPUNIT_NO_STREAM_AFTER.

include/cppunit/extension/TestSuiteBuilderContext.h:
* src/cppunit/TestSuiteBuilderContext.cpp: fixed bug #921843. This bug
was caused by a known STL bug in VC++ 6.
See http://www.dinkumware.com/vc_fixes.html <xtree> issue with shared
std::map in dll. As a work-around the map has been replaced by a vector.

examples/cppunittest/TestAssertTest.h:
* examples/cppunittest/TestAssertTest.cpp:
* examples/cppunittest/XmlUniformiserTest.h:
* examples/cppunittest/XmlUniformiserTest.cpp:
* include/cppunit/TestAssert.h: add the exception assertion macros
from cppunit 2: CPPUNIT_ASSERT_THROW, CPPUNIT_ASSERT_NO_THROW,
CPPUNIT_ASSERT_ASSERTION_FAIL, CPPUNIT_ASSERT_ASSERTION_PASS.
Updated unit test to use and test the new macros.

* include/cppunit/extensions/HelperMacros.h: deprecated the
test case factory that check for exception (CPPUNIT_TEST_FAIL &
CPPUNIT_TEST_EXCEPTION).

configure.in:
* config/ax_cxx_gcc_abi_demangle.m4:
* src/cppunit/TypeInfoHelper.cpp: added patch from
Neil Ferguson <nferguso@eso.org> to use gcc c++ abi to demangle typeinfo
name when available.

include/cppunit/extensions/TestNamer.h:
* src/cppunit/TestNamer.cpp: Fixed bug #704684, TestNamer has non-virtual
destructor.

src/cppunit/CompilerOutputter.cpp:
* src/cppunit/ProtectorChain.cpp:
* src/cppunit/StringTools.cpp:
* src/cppunit/TestPath.cpp:
* src/cppunit/TypeInfoHelper.cpp:
* src/cppunit/XmlElement.cpp:
* src/cppunit/XmlOutputter.cpp: switched to using unsigned index in loop to
avoid signed/unsigned warning in vc7.

* include/cppunit/extension/ExceptionTestCaseDecorator.h: removed dll export
on template (caused link error on vc7).

include/cppunit/tools/Algorithm.h:
* src/cppunit/TestResult.cpp:
* src/msvc6/testrunner/TestRunnerModel.cpp: added removeFromSequence
algorithm in Algorithm.h to fix STLPort compatibility issue
(std::remove use the one of cstdio instead of algorithm). Bug #694971.

* include/cppunit/extensions/TestNamer.h: fixed bug #662666 (missing include
for typeinfo).

* src/cppunit/TestResult.cpp: TestFailure are no longer passed as temporary,
but explicitely instantiated on the stack. Work around AIX compiler bug.
