GDC already uses (as in: actively, currently, in use) "Unix" for this:

Windows
- Win32
- Win64
Unix
- linux
- darwin
- freebsd
- cygwin
- solaris

Most if not all code currently including "std.c.linux.linux" with DMD,
can be compiled by using the portable "std.c.unix.unix" in GDC instead.

I was just hoping to avoid a fair amount of the needed copy and paste...
