"version" predefined pragma

[Dave]

Along the same lines as pragma(lib,...) I'm wondering if it would make sense to
add something like pragma(switch,...) also, e.g.:

pragma(switch,"-version=MY_VERSION");
version(Windows)
{
pragma(switch,"-L/SUBSYSTEM:windows:5");
}

That would act like the command-line:

C:\>dmd foo.d bar.d version=MY_VERSION -L/SUBSYSTEM:windows:5
