* 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.
