Arnout, All,

Jumping back into this old thread, after it was referenced by Maxime in
his XBMC series...

Here is a little test I did:

    $ cat Makefile
    all:
        echo "'$${buz}'"
        foo

    $ cat /tmp/foo.env
    buz="BUZ"
    echo BAR
    alias foo='echo FOO'

    $ BASH_ENV=/tmp/foo.env ENV=/tmp/foo.env make
    echo "'${buz}'"
    ''
    foo
    make: foo: Command not found
    make: *** [all] Error 127

So, it looks like neither BASH_ENV nor ENV are parsed (ENV is for when
bash is invoked in POSIX mode).

Regards,
Yann E. MORIN.
