That is not standardized.  There is no guarantee that a system allows
user interrupts at all, and no guarantee where they don't occur if it
allows them.  In Gforth they can occur anywhere.

Right, sequence points have nothing to do with interrupts.  The C
standard is very weak in many places; one of the things it leaves
somewhat open is in which order various effects occur.  Sequence
points are the concept that allows them to talk about this kind of
stuff.  E.g., consider

j = (i++) + (i++);

and

t = i++; j = t + (i++);

The first statement has an undefined (or something) result, because
it's undefined in which order the increments of I are performed
relative to the result of the i.  In the second example j has a
defined result, because there is a sequence point ";" between the two
increments.
