I think I can. Try this:
[starritt@redgum]$ touch a z A Z _
[starritt@redgum]$ ls -l
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 _
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 a
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 A
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 z
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 Z
[starritt@redgum]$ export LANG=C
[starritt@redgum]$ ls -l
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 A
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 Z
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 _
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 a
-rw-rw-r-- 1 starritt starritt 0 Oct 8 12:03 z
The order that ls lists directories and files is affected by
the LANG environment variable.
With no explicit dependency rule, items added to DIRS with
DIRS := $(DIRS) $(filter-out $(DIRS), $(wildcard *App))
are build in the same order as ls lists them. I think there must be a
depencency order that is implicity being catered for when LANG is set
to C.
Regards
