enum OS: int;
Operating system.

Note This is for cases where you need a value representing the OS at runtime. If you're doing something which should compile differently on different OSes, then please use version (Windows), version (linux), etc.

enum Endian: int;
Byte order endianness.

Note This is intended for cases where you need to deal with endianness at runtime. If you're doing something which should compile differently depending on whether you're compiling on a big endian or little endian machine, then please use version (BigEndian) and version (LittleEndian).

enum ISA: int;
Instruction Set Architecture.

Note This is intended for cases where you need a value representing the instruction set architecture at runtime. If you're doing something which should compile differently depending on instruction set architecture, then please use version (X86_64), version (ARM), etc.
