Sometimes you don't *have* setjmp/longjmp --- I've just done a basic 
port of Lua to OpenKODE, which doesn't have those functions. Luckily, 
our OpenKODE environment has a non-standard C++ extension that allows 
exceptions, which means I can at least proceed.

BTW, not having anything like stdlib or stdio does make certain aspects 
of the porting a... challenge. In particular, it surprised me that the 
file I/O parts of Lua are mixed in with the pure logic parts; I had to 
disembowel lauxlib.c quite heavily. It would be nice if we could have 
all the file I/O moved into a separate file, for ease of use in 
file-less embedded environments.
