What's the way to determine the version of the compiler being used to compile a program?

I'm trying to make code compile with 2.063, that currently only works in git HEAD because of an improvement in Phobos. I'd like to be able to somehow version() the compatibility code out in versions later than 2.063 by checking the compiler version.

would http://dlang.org/lex.html#specialtokens __VERSION__ and a
