log4cplus 1.1.0-RC10 released

I have released log4cplus 1.1.0-RC10. It contains bug fixes and also
other improvements:

- Fixed non-STLPort4 builds with Solaris Studio. Switch
'-library=stlport4' is only added if CXXFLAGS does not already
contain a switch matching -library=(stlport4|stdcxx4|Cstd).

- Fixed --disable-shared MinGW builds.

- Fixed non-working MinGW DLL binaries. DllMain() was not being called
because of missing extern "C" in its definition.

- CMake build configuration checks have been improved. (Chernyshev
Vyacheslav)

- GCC switch -O2 is only added if CXXFLAGS does not already contain
any other -O.

- Improved logging speed using SysLogAppender and Log4jUdpAppender by
optimizations in both the loggers and in common sockets code.

- FileAppender locale can now be specified in properties files using
Locale property. See FileAppender Doxygen documentation for more
details.
