Thanks for the patch.  A couple of comments:
- You should request one or more reviewers (the last ones to review the file(s) in question are a good bet), otherwise the patch is most likely overlooked/ignored.  I only noticed it due to your equivalent `gcc-patches` post.
- Please indicate which target (triple) you noticed the problem on and where/how you tested the patch.
- The `#undef` needs a comment explaining why it's needed, especially given that this is a Solaris-specific file and Solaris doesn't have/care about `_TIME_BITS`.
