Apparently ‘search_path’ has always treated "" as the current directory:
$ guile

scheme@(guile-user)> (not (not (member "" %load-path)))
$1 = #t
scheme@(guile-user)> (chdir "/etc")
scheme@(guile-user)> (search-path '("") "resolv.conf")
$2 = "resolv.conf"
(Same with 1.8.)
So we probably can’t change that.

Actually the problem was:
scheme@(guile-user)> (set! %load-path (cons "" %load-path))
scheme@(guile-user)> (with-fluids ((%file-port-name-canonicalization
'relative))
(port-filename (open-input-file "/dev/null")))
$1 = "dev/null"
I just fixed it. Comments welcome!
Thanks,
Ludo’.
