 Copy "sago/platform_files.cpp" and "sago/platform_fildes.h" to your program and make sure that the cpp file is compiled and linked.
 
+It is also possible to compile and it like:

+# C++ support
+Versions up to 3.X.X should compile with any C++98 compiler.
+Versions from 4.0.0 and up requires a C++11 compatible compiler.

+The aim is to always support the default C++ compiler on the oldest supported version of Ubuntu. This is a very basic library and it is not supposed to force you to upgrade.

+From version 3.0 UTF-8 is always used on Windows and will also be the default on almost any other system.
 Before version 3.0 Windows used ANSI encoding. Microsoft's default choice of UTF-16 is not compatible with platform independent code.
 Although the user may use an charectors they want I recommend, that the progran should not have non ASCII charectors in the soruce code itself.
