the pain points were pointer-math-related).
It's made me shy to claim that "of course it will work anywhere" when
it comes to C. Compiler writers, like all other programmers, can
suffer from a lack of vision about what's allowed vs what's required
vs what happens to have been used as a test case during development.
That's one reason for ongoing compiler development - nobody's perfect,
especially not at Rev 0.1.

Looking at what's there, I'd say that it
wouldn't surprise me that
some compilers would accept it (gcc does) and some might not,
It's legal, standard-conformant C code, so any compiler that doesn't deal
with it is broken.
