Texino build problem

[Jim Wilson]

	To avoid losing behavior with the default PROG_INSTALL -- it will
	select an install program (I don't remember which one) which does
	not work correctly.

I believe the problematic program was the `installbsd' program.  It looks like
the Cygnus autoconf sources get this right because of Jeff Law's Sept 4
patch, but I don't know if there are any released autoconf versions that
handle this correctly yet.
