No, as documented, you need a matching native compiler to build a cross Ada
compiler (e.g. build from the same 4.3 sources a native compiler first, and
then use it to build the cross compiler).

It does in general. I do not know for avr in particular.

In general, no. On a case by case basis, assuming the patch is simple and
does not make the code worse in terms of maintenance, then it can be OK.
