digitalmars.D.learn - Is __VERSION__ cross-compiler compatible?

I've seen this code used somwhere:

static if (__VERSION__ > 2048)

Does this work for all compilers, or is it DMD-specific? Also, does
DMD1 define this too? I'm trying to retain compatibility of some D1
sample code but introduce D2 support as well.

It's in the language spec, so obviously it's part of the language. But since it's defined to be the _compiler_ version, values of __VERSION__ are compiler-specific. But with the number of versions the language has been through, it would be nice if they all had numbers.... http://tinyurl.com/qayz9w

Yes.

version(D_Version2) However, because parsing happens before CC, you can't use D2-specific syntax anywhere in a code file that needs to be D1-compatible, unless you wrap it in a string mixin. Stewart.
