use setjmp/longjmp to implement exception support that is correct but
relatively slow.

<p>Also note: this specific sequence of commands won't work if you use a
function defined in the C++ runtime library (or any other C++ library). To
access an external C++ library, you must manually
compile libstdc++ to LLVM bytecode, statically link it into your program, then
use the commands above to convert the whole result into C code. Alternatively,
you can compile the libraries and your application into two different chunks
of C code and link them.</p>
