It is very important to use version control macros correctly - the
idea is that host and target are independent. If these are done
correctly, cross compilers can be built.
The host compiler and host operating system are also different,
and are predefined by the host compiler. The ones used in
dmd are:

Macros defined by the compiler, not the code:

	__DMC__		Digital Mars compiler
	_MSC_VER	Microsoft compiler
	__GNUC__	Gnu compiler

    Host operating system:
	_WIN32		Microsoft NT, Windows 95, Windows 98, Win32s,
			Windows 2000, Win XP, Vista
	_WIN64		Windows for AMD64
	linux		Linux
	__APPLE__	Mac OSX

For the target systems, there are the target operating system and
the target object file format:

    Target operating system:
	TARGET_WINDOS	Covers 32 bit windows and 64 bit windows
	TARGET_LINUX	Covers 32 and 64 bit linux
	TARGET_OSX	Covers 32 and 64 bit Mac OSX

    It is expected that the compiler for each platform will be able
    to generate 32 and 64 bit code from the same compiler binary.

    Target object module format:
	OMFOBJ		Intel Object Module Format, used on Windows
	ELFOBJ		Elf Object Module Format, used on linux
	MACHOBJ		Mach-O Object Module Format, used on Mac OSX

    There are currently no macros for byte endianness order.
