I’m using (unintentionally, as i copied from someplace) an @linux\_only macro.  
I was thinking this is from BinDeps, but this seems not to be the case.  
Where is it from, and what is the 0.6 safe and backward compatible variant?

`@linux_only` was deprecated in 0.5. Use `@static if is_linux()` instead. (You can omit the `@static` if it is not important whether the `if` is evaluated at compile-time or runtime.)

@static seems to be not available in 0.4. Is there a recommended construction that works (with Compat?) in all versions?
