[Bug-gnulib] AUTOMAKE_OPTIONS = 1.5 gnits no-dependencies

[Simon Josefsson]

After a recent CVS check out, gnulib-tool --import generate the above
AUTOMAKE_OPTIONS line.  It used to be only '1.8 gnits'.  Was this
change done intentionally?

Disabling dependency tracking seem dangerous, might it not risk not
rebuilding some files after an --import inside an existing build tree?

Could we revert it?

Btw, what is the oldest automake/autoconf version that is required by
some gnulib users?
