Hi Camm.

| The 1 vs. 3 argument signal handler is toggled by the SA_SIGINFO flag
| passed to sigaction, which I think is set on nearly all architectures
| now.  It is used, for example, to pass fault addresses to the sgbc
| code on machines where this works.  I take it this is designed to
| remove a compiler warning.  If memory serves, gcc cannot yet ( and I
| don't see how it ever could) distinguish between the two handler forms
| depending on sigactions' arguments.  So I typically make an explicit
| cast in this case, (from linux.h:)
|
| action.sa_handler = (void *)memprotect_handler; \

I'll read further on this when I have some time.

I agree about minimising the number of platform specific ifdefs where
possible.

| As always, I defer to your judgment.

Likewise,
