At least 90% of the time, when I want to exit from an inner loop in C,
there will be some kind of cleanup I need to do in the outer loop
before that can exit too. So the ability to jump straight out will
rarely be used.

 I avoid those. I structure my code like a Nassi-Shneiderman diagram, where
each block has one entrance at the top, and one exit at the bottom. Easier
to keep track of error conditions and cleanups that way.

It does mean that, strictly, the function is no longer a "structured" subroutine. But reality is usually that memory allocation failure will mean program termination pretty soon.
