[PATCH 7/13] D: Add D language support to GCC targets.
- From: Iain Buclaw <ibuclaw at gdcproject dot org>
- To: gcc-patches <gcc-patches at gcc dot gnu dot org>

- Subject: [PATCH 7/13] D: Add D language support to GCC targets.
- Authentication-results: sourceware.org; auth=none
This patch add D language support to targets of GCC itself.
These are used to declare pre-defined version identifiers in the D
language that describe something about the target that the front-end
itself is unable to obtain. Version conditions in D can be thought of
as being like the target macros of C, but that where the similarity
ends.
