The idea is:

version (linux)
{
      ...
}
else version (Windows)
{
      ...
}
else version (OSX)
{
     ...
}
else
{
     static assert(0);
}

I.e. the values should be POSITIVELY set for each system, NOT defaulted. The 
advantages are:

1. when you port to a new system, you get compile time errors for every place 
where you need to check/fix the values

2. if you want to fix the values for one system, you don't muck up the values 
for any other system

Because "linux" is what gcc predefines for Linux. (gcc also sets __gnu_linux, 
__linux__, and __linux, none of which are capitalized. It's the Linux way, not 
some nefarious plot of mine to disparage it.)
