Nice, might it be possible to have "configure" pre-generated, and possibly

Which version of the autotools are you trying to use?


Also a minor update, I experimented with disabling gcc's default promotion
of small integers (char/short) to int; and so far so good, now attempting to
also limit promoting enum's and bool's to the smallest integer type with
sufficient precision, as opposed to defaulting to int, which 99% of the time
will be a char, as most enums tend to be small; but will likely miss some
places for similar improvements, as GCC's expression manipulation code is a
bit tangled.

This would be great!

But unfortunately don't have a great degree of confidence that it would be
easily accepted, as all targets would need to be tested, and although I
don't think it would be detrimental to other targets, it may effect some of
their optimization assumptions if biased toward assuming int types, but not
sure.

Well, is there any way to make it avr backend specific? That would probably make it easier to get it accepted....
