Compatibility issues for a field that does not contain the value it
should contain? It can't get more broken than it is today, all the major
distribution versions have a kernel that null the field. So I am not
worried about compatibility. In fact I am quite happy that we can remove
this nasty ptrace hack in fesetenv/fegetenv. It even showed up on some
benchmarks.
