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 $(D version(Windows)),
$(D version(linux)), etc.

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 $(D version(BigEndian)) and
$(D version(LittleEndian)).
