D: Define custom version identifier for conditional compilation

Question

The D documentation talks about predefined version identifiers, but not how to define your own version. How do I do it?

Since this feature is supposed to be the D counterpart to C/C++'s #if/#ifdef, I doubt they would lock us to only the predifined versions.

Answer 1

You can pass a version to the compiler when building with the -version=whatever switch.
