C++ mainly differs here wrt. exception handling. This should be
independent of stack switching on Linux, i.e. just give it a try.
On Windows, Coco relies on Fibers to switch exception contexts.

The other issue with C++ is name mangling. If you compile Lua+Coco
as C++ code, you need to add three lines before the coco_wrap_main
declaration in lcoco.c (reported by Jonathan Sauer):

#if defined(__cplusplus)
extern "C"
void coco_wrap_main(void);

Actually I have a couple more pending changes for Coco 1.1.5
(nothing critical). But a new release is still on hold -- I'm
waiting for the eventual release of Lua 5.1.5 (to avoid doing yet
another patch to get back in sync). Dunno when or if that will
happen, though. :-|
