Not in the specific manner Stoustrup used it, but it's
perfectly easy to achieve the same goal. But RAII is
much less a concern when you don't have exceptions... although
I have seen people do things with setjmp()/longjmp() that
were very very clever - including hooking hardware exceptions and
hitting longjmp() with it.

Sorry, this really doesn't apply to any cases I've seen in a long
time that were not GUI programs - and I believe I stipulated to
"use something besides C++ for GUIs, please" upthread.

'Course, I'm the sort who would use a state machine to manage an
overly onerous memory allocation problem - and in C++ -  so...
