I've seen attempts at structured exception handling in C using
setjmp/longjmp but they looked awkward and were incomplete, so SEH might
not be the way to go in C. I don't know what other options may exist.
I know of only two C mechanims, either signals+handlers or setjmp+
longjmp. Using signals is coarse, and will make it hard for user code
to know better what happened. It might be hard to know it happened in
GMP when a signal comes out-of-the-blue.
Setting up (an array of) setjmp buffers might also be weird. I don't
know how it interacts with (1) threads or (2) C++. I suppose threads
will be no problem if done right, but it might be a bit prone to errors.
