-# Determine how to determine the precise cause of a signal, for example
-# division by zero.
-# - SUSV2 and POSIX specify the use of sigaction with SA_SIGINFO and a member
-# void (*)(int sig, siginfo_t *info, void *context) sa_sigaction.
-# Linux (2.2.x and newer) and Solaris implement this.
-# Linux (2.4.x and newer) on i386, m68k, sparc, sparc64, ia64 actually
-# deliver FPE_INTDIV.
-# - Without SA_SIGINFO:
-# - Linux on m68k calls the handler as
-# void (*)(int sig, int code, struct sigcontext* scp).
-# For division by zero, code would be VEC_ZERODIV<<2.
-# - Linux on sparc calls the handler either as
-# void (*)(int sig, int code, struct sigcontext* scp),
-# code for division by zero would be SUBSIG_IDIVZERO, or as
-# void (*)(int sig, siginfo_t *info, void *context).
-# Which one depends on a process specific flag in the kernel.
-# - Linux on sparc64 always calls the handler as
-# void (*)(int sig, siginfo_t *info, void *context).
-# - FreeBSD on i386 calls the handler as
-# void (*)(int sig, int code, void* scp, char* addr).
-# For division by zero, code would be FPE_INTDIV.
-# - SunOS 4 calls the handler as
-# void (*)(int sig, int code, void* scp, char* addr).
-# - Solaris?
-# - Irix 5, OSF/1, AIX call the handler as
-# void (*)(int sig, int code, struct sigcontext *scp).
-# These are so many OS and CPU dependencies that we don't bother, and rely
-# only on SA_SIGINFO.
