diff dmd/root/root.h @ 1372:229e02867307

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix format-string bugs by adding __attribute__((__format__)) in all applicable places and fixing all warnings my gcc produced. Among other things, this should fix several segfaults (including one I just ran into).
