Make sure that you do need each #include present in this and any other new file. Since 2008 a lot of includes of tm.h and toplev.h have been removed and diagnostic-core.h introduced as an alternative to diagnostic.h for many users. If tm.h is needed, it's good to have a comment on the #include explaining why (which target macros are used, for example), since we'd like to avoid unnecessary tm.h includes.
