24.3; load-path and environment variable EMACSLOADPATH |

The node "Library Search" suggests to to set EMACSLOADPATH to some
user directory such as /home/foo/.emacs.d/lisp. Yet this does not
agree with the docstring of load-path and emacs fails miserably if
one uses
export EMACSLOADPATH=/home/foo/.emacs.d/lisp
The proper meaning of EMACSLOADPATH seems to be the one given in the
docstring of load-path saying that EMACSLOADPATH overrides the
default value of load-path specified by file `epaths.h' when Emacs
was built.
The docstring of load-path also says that an element `nil' means
"try default directory". Yet what is the "default directory" in this
context? default-directory is a buffer-local variable with default nil.
I looked into this because I was looking for a way to _extend_ the
emacs load path in a Makefile generated via autoconf.
Autoconf uses the shell script elisp-comp to compile lisp files.
This script uses
echo "(setq load-path (cons nil load-path))" > script
$EMACS -batch -q -l script -f batch-byte-compile *.el || exit $?
In such a hard-coded setting I cannot (easily) extend the load-path via
the emacs option --load. But the purpose of loading the file script
is not clear to me either.
