You can have exceptions in C too.

I've used it a bit while contributing to Baz 1.x (the fork of tla).
The library used was cexcept ( http://cexcept.sourceforge.net/ ).

As you mention, jumping is the easy part, and cleaning up is the hard
one. Baz was using talloc, hacked to somehow work with cexcept. The
mini-library doesn't seem to be available as a tarball anymore, so I
did the checkout+targz in case someone's curious to have a look, and
lazy enough not to install baz to get it:

http://www-verimag.imag.fr/~moy/tmp/talloc-except--2.0.1--patch-2.tar.gz

This stuff is not supported anymore, but very small anyway.
