That's an Autoconf thing; gnulib doesn't use it.  I think it's
not needed in config.h, and will look into removing it at
some point.  In the meantime, don't worry about it; it doesn't
affect Emacs.

That's another Automake thing.  PACKAGE should be "emacs",
and VERSION "24.0.50".  VERSION is used in some auxiliary
programs like lib-src/etags.c.  Emacs doesn't use PACKAGE
anywhere now, but perhaps it will someday.

You needn't worry about those.  They're already gone from
the Emacs trunk.
