Building a cross compiler from scratch "just works" (as in all one
has to do is "configure, make all install") if all of binutils, gcc,
newlib, libgloss, libstdc++, etc. are siblings.
[At least this use to "just work".]
The number of hoops one has to go through when this isn't the
case can be pain

A question for the general group.
Is it really the case that it's ok that a testcase clobbers boolean_true_node
and sets overflow? (and is this one case of a more general problem?)
If that's not unintended, ok, but it seems confusing (aka source of bugs).
Or, which is certainly not unexpected, is
It seems like there's a whole range of issues once boolean_true_node
(or any such global tree node) has been clobbered.
