bug#5447: 23.1.91; load-file fails for C:/the-file.el.gz

[Eli Zaretskii <eliz@gnu.org>]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

 emacs -Q
 M-x load-file RET C:/the-file.el.gz RET

This signals an error: Wrong type argument: consp, nil.  The traceback
is as follows:

  Debugger entered--Lisp error: (wrong-type-argument consp nil)
    jka-compr-load("c:/the-file.el.gz" nil nil t)
    apply(jka-compr-load ("c:/the-file.el.gz" nil nil t))
    jka-compr-handler(load "c:/the-file.el.gz" nil nil t)
    load("c:/the-file.el.gz" nil nil t)
    load-file("c:/the-file.el.gz")
    call-interactively(load-file t nil)
    execute-extended-command(nil)
    call-interactively(execute-extended-command nil nil)

This problem does not happen for files not in the root directory of a
Windows drive, e.g., C:/Temp/the-file.el.gz

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
