Include/cppunit/Portability.

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.

   New in CppUnit 1.10.4:
   ----------------------
 
+
+* Portability:
+
+  - Support for embedded visual C++ 4 added. For this purpose, CppUnit now
+    provides a very simple stream implementation if none is provided.
+    This should also help porting on other platforms which have STL but
+    no stream support. Just make sure that CPPUNIT_NO_STREAM is defined
+    to 1 in your config header.
+
 * Bug Fix:
 
   - cppunit.m4: patch #946302, AM_PATH_CPPUNIT doesn't report result 
     if CppUnit is missing.
 
+* (Possible) Compatiblity break:
+
+  - All text output is now done on cout() instead of sometime cerr & 
+    sometime cout depending on the component.
+
+  - OStringStream definition has been removed from Portability.h. This
+    means that <sstream> is no longer included, and that ostringstream and
+    string might not be defined. In practice this should have no impact 
+    since those includes have been moved to other CppUnit headers.
+
+* Notes:
+
+  - CppUnit now uses the alias OStream when refering to std::ostream for 
+    portability.
