Did you mean `__signalfn_t`? It looks like asm-generic/signal-defs.h depends on `__sighandler_t`, but they themselves do not define that typedef. (unless something is really wrong with my grep-fu).

We're inconsistent about our use of uapi headers.  I would like to try to use them more, but I suspect most libcs have run into issues with the uapi headers.  Probably a longer conversation to have there...
