None of the above) Change syscalls.master in the same way as <signal.h> to use "struct __ucontext *" instead of "ucontext_t *", and maybe forward-declare "struct __ucontext" in <sys/signal.h> so that sysproto.h can see it (sysproto.h really shouldn't include <sys/signal.h>, but it doesn, and I think the forward declaration isn't be automatically generated [yet?]). If you change the sigreturn line in syscalls.master, please fix the name of the parameter there and in the functions (it is still sigcntxp, but should have been scp and should now be ucp). Also try adding `const'. Almost all of the pointers to input parameters in syscalls.master are missing `const' and adding them tends to require const poisoning all over the kernel, but `const' should be used for at least syscalls newer than C90.
