Suggested minor changes to build orbitcpp on Windows

["Tor Lillqvist" <tml iki fi>]

With the attached minor changes I managed to build orbitcpp on
Windows, and as far as I could see, it worked fine. OK to commit to
trunk?

+
+	Fixes to build on Windows.
+
+	* configure.in: Use the --enable-runtime-pseudo-reloc linker
+	switch on Windows. Needed by the test programs.
+
+	* orbitcpp/idl-compiler/Makefile.am
+	(libORBit_idl_backend_cpp_la_LDFLAGS): Use -no-undefined so that
+	libtool bothers building a DLL on Windows. Should not hurt on Unix
+	either. Use -module -avoid-version instead of specifying any
+	libtool versioning information. Using -version-info means that on
+	Windows the DLL basename gets libtool versioning cruft inserted,
+	producing a name like libORBit-idl-backend-cpp-10.dll. Thus it
+	would be found using just the "-l cpp" flag to orbit-idl-2.
+	(libORBit_idl_backend_cpp_la_LIBADD): Link with ORBITCPP_IDL_LIBS.
+
+	* orbitcpp/idl-compiler/types/Makefile.am (INCLUDES): Drop extra
+	trailing slash which confuses mingw.
+
+	* orbitcpp/orb-cpp/Makefile.am
+	* orbitcpp/services/name/Makefile.am: Use -no-undefined so that we
+	do get a DLL on Windows.
+
+	* test/Makefile.am (check_PROGRAMS): client_server.cc uses POSIX
+	APIs, so don't bother with test_runner on Windows.
