Re: [HACKERS] Proposed autoconf change: rip out search for 'install'

   The minimum-change, safest way to address the issue is to take out
   configure.in's search for an install and always use install-sh
   unless the user specifically overrides that.  Using AC_PROG_INSTALL
   looks to me like it introduces more risk; there's a possibility that
   it will settle on an install that isn't really compatible, which is
   the same problem we've got now.  On the other hand, there's a lot to
   be said for using standardized solutions, and AC_PROG_INSTALL is
   presumably pretty well tested...

Why not just go with AC_PROG_INSTALL since it gets tested by all the
other gnu software installations anyway.  If there are special cases
that it doesn't grok we can always put it inside a conditional based
on a --with-install=/your/favorite/install/program configure option.
I doubt we really will need that, though.

Cheers,
