Then there must be something special about your installation. ;-)

The source of all this trouble is in the way `make install' from
fileutils creates and installs the symlinks (or does not ;).  The
binary distribution has the following programs and symlinks:

	real name   dos name
	~~~~~~~~~   ~~~~~~~~
	dir     <-- d
	vdir    <-- v
	mkdir   <-- gmkdir
	rmdir   <-- grmdir
	install --> ginstall

This is also what gets built in the src directory.  All the programs
are built with their real names except for install which is actually
built as ginstall to save the makefile from exploding.  As each
program is built a symlink is created to give above structure.

`make install' copies all the programs into the bin directory and
transforms ginstall to install during the copy.  There is nothing in
the makefile to copy or create symlinks in the bin directory.

So what is left in the bin directory is the old symlinks pointing to
the new programs - except for install & ginstall, which are both
programs but new & old versions respectively.

This means after building and installing filutils with `make install'
we are left with the old version of ginstall, which *appears* to be
broken wrt /dev/env/DJDIR because everything else works fine.

The really simple fix is to just manually copy *.exe from src to bin.

Below are two diffs which correct this behaviour.  The first diff adds
support to the makefile to create an arbitary number of symlinks at
*install* time.  This leaves programs in the bin directory with their
real names, and symlinks for the dos versions:

	real name   dos name
	~~~~~~~~~   ~~~~~~~~
	dir     <-- d
	vdir    <-- v
	mkdir   <-- gmkdir
	rmdir   <-- grmdir
	install <-- ginstall

The optional second diff removes the feature to create symlinks in the
src directory at compile time, in case this causes confusion.

With filutils 4.0 looming this is not too relevant, but I hope it may
be of use to someone.  Filutils 3.16 port is 3 years old, how can this
be hidden for so long?  Please don't say I've fixed a non-problem. ;~/
