+ * Calling conventions
+ * The System V ABI is one of the major ABIs in use today and is virtually universal among Unix
+ * systems. It is the calling convention used by toolchains such as i686-elf-gcc and x86_64-elf-gcc. 
+ * 
+ * Windows builds often use "project files" and are less transparent and more ad hoc than Makefiles.
+ * As an example, the driver crashes by calling a callback previously register via .NET. Therfore 
+ * on MSVC, the calling ABI is defined. On other system (UNIX), the macros below are left
+ * empty.
+ * 
+ * _WIN32 is always defined for Win32 or Win64 applications.
