LC_ALL=C will "unlocalize" strings get from the standard libc functions
(time format, number formats, etc); for actual translations done trough
gettext you alos need LANGUAGE=C
In other words, all automatic scripts must define
LC_ALL=C
LANGUAGE=C
any time they need to ensure a known state when running an external program
and reading back its output.
Note also that if such script interacts in some way with the user (printing
messages to him etc) it must not be completly unlocalized, so not
export LC_ALL=C
export LANGUAGE=C
but rather some
.....
system("LC_ALL=C LANGUAGE=C foobar parameters");
....
Note also that even if the output is just numeric the "unlocalization" must
be done too; some locales may format numeric output differently (well,
currently that isn't really very used; but with the outcome of glibc 2.2
it will finally happen)
