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.
