There's still a bug related to signed zero support.
I think I've fixed that now on mob [1]. In particular +x is regarded as
no-op for floating point types (for integer types it's still x+0 so that
the promotions still happen automatically). And unary -x is now expanded
as subtract(-0,x) for floating point types (hacking in real support for
unary operations would have been more complicated and would have entailed
changes in all backends).
I've also included your tests in tcctest.c.
Ciao,
Michael.
