+ INTERNAL:
+
+ - Some cleanup in the exclude code has saved some per-exclude memory
+ and made the code easier to maintain.
+
+ - Use rsyserr() in the various places that were still calling
+ rprintf() with strerror() as an arg.
+
+ BUILD CHANGES:
+
+ - Added a "gen" target to rebuild most of the generated files,
+ including configure, config.h.in, the man pages, and proto.h.
