obsolete and/or redundant files in Automake CVS?

[Paul Eggert]

In looking at the latest Automake CVS I noticed that ./install-sh is
obsolete (as compared to Autoconf 2.54).  Does that file need to be
distributed any more?  lib/install-sh is up-to-date and it seems to me
that ./install-sh should not be needed any more.

A similar situation occurs with mkinstalldirs vs lib/mkinstalldirs,
and with mdate-sh vs lib/mdate-sh.

Slightly different is the case of ./missing vs lib/missing; in this
case the files are identical but surely ./missing is redundant.

I also noticed that the following files seem to be obsolete compared
to Autoconf 2.54.  I assume they're supposed to be identical.

lib/Automake/General.pm
lib/Automake/Struct.pm
lib/Automake/XFile.pm (the only difference is Automake vs Autom4te?)
