However, they only need to visible given an explicit:

#include <sys/ucontext.h>

I have a half-done webrev that avoids defining them via the usual route they
turn up (sys/signal.h), after getting annoyed at having to "fix" #define ERR in
so many applications, but never got around to finishing it.

There's no good reason that we can't mostly solve this problem, other than lack
of time...
