this means that the Linux kernel and libstdc++ can't reliably use
__builtin_signbitl, as whenever the operand can't be constant folded

_signbitl.
Indeed, I'm *very* happy to see that finally we can rely on this
feature! Thanks.
Any chance we can have it also for 4.0? ;) In any case I promise to put
it to good
use in complex::pow, at least.
Thanks again,
Paolo.
