   2 / The SCO signal stuff seems to be weird.  The POSIX stuff appears to
   3 / "extended" system calls, and use values in eax and edx.
   4 / Like most of the other signal routines, it takes a function pointer
   5 / in %edx.  Since this function is terribly small, I am including it
   6 / in all of the ones that need it, for now at least.  Seems silly to include
   7 / a whole file for two instructions.
